Diamond's Grill in Oshawa

My kids and I love coming to this family owned diner. Always friendly, great food and portion size is large. The owner always remembers us. I recommend!!

This place is wicked. You gotta try the world famous burger jay makes you won t regret it.

Great food and friendly owner!!! Elvis sandwich is the best! Great to support local entrepreneurs.

Excellent all around!

Jay is the best.

Food is fantastic Staff is very friendly and entertaining. I love the 5s diner theme they have going on.

I haven t been to Diamond s Grill in many years. The food and the atmosphere was the same! It s always delicious food and the portions are huge! The prices are good! The service was amazing! Will always recommend it to anyone!

I find the Diamond Grill very friendly and the food and service very good. I asked for pancakes with strawberries and was told that strawberries are not on the menu. Next week I came back and I asked for pancakes and was told that they have strawberries.

I ordered the Sinatra burger as takeout, without the cheese but adding mushrooms and banana peppers. The burger tasted delicious but the toppings were scarce, counted only 3 mushrooms and 4 peppers on the entire burger and the fries hadn t been seasoned at all. They could at least put some salt on them to make them taste good, ended up throwing them away.

Great little local diner. Very friendly staff

When me and my husband first moved here, this was the 1st place in Oshawa we went to. We had the best breakfast ever and the service was amazing! They give you more of a homey feeling. Every occasion now me and my husband gets breakfast here and we always have the same reaction when we first came. I can not recommend this place enough!!

I use to love this place tell I seen all these photos and videos of the owners all over Facebook today. Never will I eat here again. Anyone who puts children in danger is awful.

This place is disgusting, they have bugs in the kitchen and know about it and yet still cook with them in there, the owners are not nice people and are rude every chance they get. Do not eat here unless you like to eat bugs

I would never eat at this place due to watching videos and pictures of how they treat their tenants and their tenants kids. they dont know everything about how to run anything.

The food was absolutely garbage, I saw 5 roaches on his stove, food, and the counter tops! There was even maggots in my food and I was absolutely disgusted. DO NOT EAT HERE! Parking: N/A

A cute little family run 50s themed diner, amazing prices, service and food! Its our family go to breakfast spot, something of which my hubby takes seriously lol Go! You wont be disappointed!

Excellent food! Used to go here all of the time in high-school and glad to see it is still open!

One of my favorite places, especially for breakfast. Burgers and poutine are great too.

Its always an amazing experience at Diamonds. I love the omelets and the homefries. Pemeal is always cooked perfectly. It is always a friendly, welcoming environment. I recommend it the omelets and I will be returning. Dietary restrictions: Has gluten-free options and gluten-free bread

Great food and super friendly owners! Been coming here most weekends for years. The breakfast is top notch and the conversation is just as good! Highly recommend!

Dont let all those fake negative reviews fool you. This place is a gem, always friendly, generous amounts of food and always delicious! Would recommend this place to everyone!!!

Got some early breakfast here. The portions were great, the food was good

Tiny diner with great classic diner meals. Good prices, good food and fun atmosphere. Our food was good and piping hot and was on the table quickly. It s just in a small plaza but don t let deter you. Great place to eat!

Great food, huge portions, owner and server are very nice.

Delicious!! Food was fantastic service was great, very friendly we will definitely be back.

A great casual eatery. Service was 2nd to none. The food was delicious.

My husband and I just enjoyed a lovely breakfast at Diamonds Grill. The food was fantastic, the bacon was real bacon and the home fries were fantastic and the owners were super nice. Our first time there but definitely not our last

Great live band and atmosphere

I love going for breakfast here and they have awesome burgers too if you feel like stopping in for lunch or dinner

A Gem hidden in a plaza. Food is excellent and the homemade burgers are one of the best in the city! Breakfast is also worthy of a cross-town trek! Generous portions, great quality, and the service is the best part! Ambience is very much a 50s diner feel, but the dining area is quite open and somewhat small. Prices reflect the quality and quantity of the meals! Will be going back often. Parking: Large plaza with ample parking. Kid-friendliness: Owner and staff are very kid-friendly, and the menu reflects many kids favourites. There is no reason not to bring kids of any age here.

Excellent breakfast / brunch spot in oshawa. Owner is absolutely wonderful and friendly and the plate portions are more then excellent. Food is fresh and tasteful!

I ordered breakfast and the potatoes were undercooked and no flavor. Bacon fatty and not crispy. Came with a free poutine and rhe fried were not cooked.

The best little diner in town. Fresh home cooked food, fantastic service and the owners genuinely care about their customers and the food they serve. We are regulars for life!

During our visit and 3 months stay in Oshawa from September to November 2022, we visited Diamonds Grill diner about 4-5 times. We enjoyed the hearty, sumptuous breakfast at all times. It is a simple, homely diner with red tiled walls, black-white diamond tiles flooring, red chairs. On entering the diner, one feels as if one has entered the era of the sixties. Gramophone record discs and posters of yesteryear musicians and actors like Elvis Presley and Marilyn Monroe adorn the walls and soft music is played in the background. There is an all-day breakfast menu. We always enjoyed a hearty, sumptuous breakfast - 3 eggs sunny side up/scrambled/omelette, with sides of ham or bacon and home fries, pancakes, french toast and of course loads of coffee during the meal. The dishes were perfectly cooked. The diners Sri Lankan owner, Jagadeeswaran, popularly called Jay, is very friendly and amiable, welcoming you with a smile and striking up interesting conversations. He has a remarkable ability of remembering the preferences of regular diners. We had a very enjoyable dining experience at Diamonds Grill and hope to patronise it in future too whenever we visit Oshawa.

Ordered the clubhouse sandwich and the bread was moldy... One of the worst establishments I have ever been to! FILTHY!

Never order from this place. I couldnt believe the state of the food, nothing we ordered seemed fresh at all. Worst of all my meat was undercooked. Terrible restaurant!

Thid is a cosy little place in Oshawa with amazing brunch options. Love the food and and the reasonable prices but what makes us go there regularly is thr friendly service and conversation!

Not very friendly! Couldn t order a coffee at 4 pm. Sorry no coffee on . Refused to make any. Thought it was all day breakfast. Oh well!! Bakery next door is good!

Comfy chairs, good coffee. It was busy almost full. Service was still pleasant and in good time. Food was delicious.

Everything was yummy! Bacon was really good and so was the price and company. !! The owner is a really cool guy

Decent price for breakfast. Considering everywhere is ridiculous for prices. Waitress was very pleasant

Great food , service and atmosphere..highly recommended.

I came here with a friend to relax and have a meal. Unfortunately the food was bland. The only reason im giving two stars is because the staff was very polite. Maybe over polite. My buddy and I were not even able to conversate with one another as the lady worker just kept talking to us. She was talking to us while we were waiting to eat, while we were eating and pretty much the entire time we were there. The food was also overpriced and on the expensive side. I would back it up if it tasted good but it was bland. My buddy got the hot dog is supposed to be like a philly. The hot dogs were the ones you see at the local supermarkets small and skinny. They just tossed in a bunch of those and put in some cheese. I rather go to the store a few doors down from them. They have great prices great food and the staff also let you eat in peace when your not trying to engage in conversation.

This store that so awesome , everyday i order breakfast thats so delicious, and the beef thats so good ,

Honestly the best breakfast I have had at a restaurant. It has amazing classic food for a great price. Kid-friendliness: The owner is so friendly and will treat you with 5-star service.

Cute diner with with a family vibe to it

Had a wonderful time eating here with my family. Dont be fooled by the rough aestetic, as it is an older restaurant, the food and service here was great. The burger I ordered was easily one of the best and the food was all cooked to perfection and presented well. We were checked on many times while we ate, so we always had full drinks. And they even serve breakfast all day. Above all else, the prices were very reasonable, so we didnt spend too much. I would highly recommend this place for breakfast lunch and dinner! :)

Went in for Fathers day breakfast. Super friendly and polite staff, good old fashioned breakfast. We had the following meals: french toast, home fries, bacon chocolate chip pancakes, home fries, bacon eggs benedict with peameal bacon We all agreed they were the best breakfasts wed had in a while. My only suggestion - having a radio playing in the background would be a good idea.

Fantastic food from breakfast to dinner and in between everything is great. Service is friendly and very helpful.

Showed up on Canada day at 8am for breakfast with my dad, Google said they opened at 8. I later found out the owner wasnt going to open until 9am as it was canada day but since we were outside waiting he didnt want to disappoint and let us in early. We both had the breakfast special which was around 7-8$ for eggs, I had sausages/ my dad had bacon, and home fries. For the price the amount of food I got it was amazing! Lastley the owner was very friendly and happy to be there with us.

Had an awesome experience here with my nefew today! The food was Fantastic! Very friendly and warm hearted service! Compliments to the chief and server with a good sense of humor! Thanks again guys and keep up the amazing work God bless!!!

Home fries werent cooked, still soft potatoes, ordered 2 breakfasts, one with sausage the other with bacon. Both came with bacon eggs were broken all over the rest of meal, Bacon was not cooked very well, it was still pretty pink.

This is a hidden gem that no hipsters will ever find and ruin, but they should if they knew anything about good food, ambiance and great service. Diamond D has all three in spades and the best blueberry pancakes we ve ever had. 10/10 do recommend.

My daughter has been bugging me to go to this place for breakfast. She loves going there. Went with her Monday. Amazing little place, sparkling clean with a wonderful casual atmosphere and excelent service. Breakfast was really great and nicely presented. Thought finally a place that knows how to do bacon well done. Coffee very good. Certainly will be my go to place going forward. If in the area give it a go. You wont regret it. Kid-friendliness: Casual atmosphere where I ithink parents would be comfortable taking young kids.

On the morning I went with my family it became very busy. Only one person was taking orders, cooking & serving. The breakfast wasnt very tasty. The burger was dry without any kind of sauce but the chicken wrap was excellent. I will give this restaurant another try. Everyone has bad days, right?

So rude ,impolite staff !!!

Ordered a takeout breakfast, potato is a bit too greasy and a hair in the food is unacceptable, straight to the bin ans never go back!

I couldnt believe the food we ordered NOT fresh at all. Terrible restaurant!

Great environment and amazing food! The owners were extremely friendly and funny, made the experience even more enjoyable.

Huge meals Fresh food All sauces gravies Chef made Food : 5/5 |

Old fashioned diner with a good man behind the grill.

Only been for breakfast, but it was fantastic! The atmosphere is great, the owners are a blast. I will definitely be back.

Amazing!!!! Everyone should come have breakfast at the Diamond Grill. The food was amazing and the owners were super super friendly. 10/10 experience

Jay does it up good!! Whether its breakfast lunch or dinner, always good portions, always tastes great!!

I just pulled into the parking lot and was reading menu to place order to pick up and staff come out and rudely ask me too move. I was only parked for about 2 minutes. Not ordering now..

I ve been here twice both times got the same order I got a Philly cheesesteak and a chilli both quite delicious chilli a bit spicy but I like it like that. For me it was well worth the money and I ll definitely be going back again maybe trying something different.

Delicious food, generous portions and well priced. Owner is a lovely person!

This restaurant/grill is absolutely awesome. I ordered food for delivery to the freightliner dealership, truck was in the shop and I had no way to get anywhere for food, and the delivery company didnt come through, so a friend of the owner came through to help out. The food was just perfect, the price very reasonable. If your traveling through Oshawa stop and have a great meal, these people will take care of you. This Texsan thanks you very much, and have a great day and God bless.

Service was excellent and food is very delicious.

Precious stuff

Great food good price, staff super friendly

Amazing food, amazing people. Overall an amazing experience. I recommend this to anyone looking for a fantastic lunch!

Best breakfast ever thank you jay

Always great food Oshawa location for many years Cant go wrong with a meal from Diamonds Grill

Best service in town and the food cant be beat

Eggs Benedict were great.

Great breakfast

Diamond Grill, is the best breakfast in all of the GTA. My finaceé and myself stumbled upon this small diner and was amazing by the quality of food that is ordered in. The all-you-can-eat breakfast made hot per order is an experiance that is unlike any other. The service from the owner, absolutely amazing. Prices are second to none! The atmosphere is exactly what you are looking for in your next go-to diner. I strongly suggest you do yourself a favor and check it out.

Always a nice breakfast u can get the diamond breakfast for under $10

The best hidden gem

Great place. Good tasty food for an excellent price. Very clean also

Not a bad place. But you can clearly see that this place has been worn down due to the Covid pandemic. The place is a little run down and not as busy as what possibly could be. The owner is trying though. He was the only one working as probably not making enough money to afford staff. The food was good and customer service was fine. Not a bad place for trying to get out from under the devastation of the pandemic but I will not be returning.

Great warm staff. Excellent food prepared the way you want it.

Went for afternoon all day breakfast. II thought it might be a bit pricey at $35 for two people, but it was very good.

Nice place with 1960 decoration and tasty food!

Absolutely disappointing. Ordered from skip, not only were there missing items but the food was horrible. Lettuce on burger was rotten and tomatoes were definitely not good. who puts a hot burger in with a salad???

We live this place ! Been eating here for 13 years since I moved to Oshawa Jay has the best food and service

Friendly , clean , good portions and prices. Certainly Worth a visit.

It is unfortunate that i have to give this restaurant an unfavorable review .. awaited a fair amount of time for them to at least call with an apology.. however instead of contacting the health department I have decided to be more lenient by posting a truthful review as we are all struggling in these times ..this is not just a case of poor food quality or poor service but dangerous ...we order breakfast delivery today and completely shocked.. food arrived cold as ice.. needed to be reheated... Pancakes were burnt and inedible.. long hair in eggs... But final shock was the steel wire likely from a steel wool scrubber...I dont think I need to preach about the dangers this thin piece of long wire could have in the human digestive system... Hence we cannot support this restaurant going forward... Shame how a little apology call could have gone a long way here... Showing concern for consumers

The food was delicious, the owner is friendly and I love the nostalgic atmosphere. What more could ask for really

Unfortunately I didn t check the closing time and tried to call in to order a sandwich. Rather than pick up and explain they were sorry but have cleaned up for the day they just repeatedly hung up. I realize my mistake, but that s just poor service.

Great breakfast!

Favourite diner in town! Eggs bene are to die for. Would eat here every day if my hips could handle it!

Best burger in Oshawa

First time ordering from this establishment and I was quite disappointed. Ordered Philly cheese steak which was lacking cheese and the meat they use was fatty and undercooked, meat was still red on the inside and chewy. For the price I paid i would have expected more than a kid sized portion of fries. How do you expect people support your local business if you continue to charge 18 dollars for a kids size meal? Found chunks of fat in my wrap also. Gravy ? Tastes like fish and is absolutely unappealing. Having over 15 years experience in restaurants across Ontario i never would have even considered sending this mess out for delivery. So after spending 50 dollars or more on food for my family , I hope you enjoy it , because you definitely will not be getting another cent from this foody.

Ordered soft eggs and scrambled eggs.better off at ncdonalds.bacon was burnt n crispy eggs were scrambled into a omelette style.to much cinnamon on pancakes n french toast was edible. Wouldnt recommend

Amazing food, great prices, big portions!! Definitely my new go-to restaurant.

This is the best restaurant to go to for breakfast, been going occasionally for years and hope its around for years more.

Had a delicious breakfast with our family today at Diamonds Grill. They are friendly and the food was so good. Loved the environment and the really cute stereo speakers playing the classics. Food was made to order and quickly without compromising quality. Our son loved your drink suggestion. His very first time drinking coke out of a bottle instead of a can. Thank you for your service. We will be back very soon!

Great breakfast Friendly owners...All the best to you my new friend... the 3 old guys

Today i had the best burger ever and the fries are amazing! My kids love it! Thank you jay for the most amazing food as always

Good food good service and very friendly staff (Jay)

Nothing really special here

Unbelievable delicious food. The service is amazing, friendly, fast and kind. Best breakfast in Oshawa.

Best pancakes we have ever had.

Diamond grill makes the best breakfast and always remembers my order and very friendly ! Highly recommended

Very nice place

Great atmosphere, great people and good service. I did not enjoy the breakfast. Was too greasy for me.

I want to share... I appreciate the honesty the owner demonstrated after I had order a delicious eggs Benedict. We spoke about the good quality of the hollandaise..I assumed it was homemade. He modestly said no it was a high grade prepared sauce. Thank you sir, I truly appreciate being dignified with honesty...I recommend this place!

My husband and I ate here for the first time this morning. The food came fast, it was fresh and it was hot. It was very tasty, eggs over medium were perfect. Portions were large and the price fair. The gentleman behind the counter, I believe to be the owner, was very friendly, followed the covid protocols and the restaurant was clean. I enjoyed this 50s diner and will return for more!

Wow, hands down one of the best burgers I have ever had. I had the Elvis burger with peanut butter. Sooooo good. Freshly made, bun was so fresh and the homemade fries were on point. Do yourself a favour and try this place. Super friendly staff as well. We will be back the next time were in Oshawa!

Great owner, great service, tons of food. I will return next time Im in the area! Thanks

Delicious breakfast, great service!

Amazing food. My family has been coming here after Church on Sundays for breakfast for years. Jay and his wife are amazing hosts!

Food is delicious! Prices are reasonable! Coffee doesnt taste like engine fuel like most places. Owners are very personable and will chat with you like old friends. Will return again and again

Great specials for breakfast. Also for kids they have a 5 dollar menu of your on a budget.

Great breakfast and a great price. Cant beat the food and Jay the owner is a great guy. Will be back often. Our new breakfast place 100%.

Diamonds Grill is fun and cozy. Nice 50s vibe. The food is delicious.

While we were cruising around originally to look at a house when we came across this place we are hungry we came in to grab something to eat the establishment is very clean its got that cool looking retro look when you look at the menu easy to select description of the menu is amazing you just cant wait for the food to come to your to your table. The fries perfectly cooked food amazing all I got to say its worth every penny to come into this place I want to thank the owner for being a great host I really like that retro Pop shop thing going on just perfect to go down with the food. Were looking forward to our next Adventures into this establishment if youre driving by Drivin get yourself some good food

Very friendly staff, chill atmospheric, good food at good prices.

Awsome breakfast very pleasant and good food

Bought a eggs Benedict, was super soggy and not put together very well, might as well donating the 14$ to something worth while

Great breakfast! Ready fast for pickup and portions were decent. Not over salted but was seasoned nicely. Also the owner was really nice.

Thats how breakfast should be. I chose the pick 5 special and everything was perfect. It was hot, and the portions were generous. The gentlemen cooking was a nice guy and the food was prepared very quickly. I will be returning often when in the area.

Food is great with large portions.

Had the burger and fries. Burger was homemade and made with real cheese. Fries were like a food truck. Tasty.

Awesome lil spot for bfast . Never had any issues. Great service good prices

Great place, Great food, Nice guy

Our neighbor took us here and stands by this diner. J the owner is very humble. The place is simple, clean and the food is amazing and is big portions. We will come again soon. Thank you

We order from here often. It is mine & husbands go-to place to get breakfast, and also a place me & a good friend love to go to as well. Great food, great service.

Jay is superb with cooking home style

A poutine made with shredded cheddar and a reuben made with ingredients from loblaws for 31 bucks...oof

Thanks for asking. The food is always great, and the price is right. The owner is doing the cooking and serving clients he is very friendly and helpful also polite. Havent been there in a long time but hes still as cheerful as ever.

Food is fresh, hot, homemade soup. Friendly service, always smiling, curtious, and owner helps out his community. We love going there.

Great food, Great service. Great experience

Avoid this place like the plague! The owner and his wife are some of the most unpleasant people I ve ever had the unfortunate instance to meet. They must have something mentally wrong with them as it seems they are quick to anger and quite petty. Lots of better options in the area. If I could give zero or negative stars, I would.

I love this spot. Great breakfast and the owners are over the moon nice. Highly recommend

Good food,at Fair price

Love the breakfasts, great price and owner is super nice. Great service!

Burgers great fries are small 1_2 expensive

This place is amazing! The price are super cheap and the dishes are super big! The staff is very friendly and the food is delicious! If you driving by this area you must stop at Diamonds grill! Thanks so much!

Fantastic atmosphere, great food and the Owner, Jay is a fantastic host. My wife and I had a late afternoon craving for pancakes and decided to give Diamonds a look. We werent disappointed. I had the Grand Slam and my wife had the Diamond Special. Both were quickly, yet expertly prepared fresh. Looking forward to our next visit.

Busy little place. Breakfast was fresh and fast. Server was friendly. Reasonable prices for good potion size.

Food is good small quiet place

Awesome atmosphere and great service. They make you feel at home! Will be coming back!

Will definitely be back. Great friendly service and fellow patrons. A yummy local bite on the cheap.

Cute location and nice stuff but the food was ok at best.

Its good food

Expensive for a diner

Food was good and made quick. Nice little diner but a bit expensive

I very much enjoy the patrons that come in. The atmosphere is a welcoming one allowing for good topical conversation(s) and the sharing of opinions. Jay is an excellent chef/host and his corn beef is the best Ive had in Durham Region.

The best burgers in Oshawa. And great service.

Took my family here for breakfast today. Nice people but unfortunately I was served a soupy undercooked pancake. They offered to make me another one but I had lost my appetite after having swallowed some of the uncooked batter. I also was concerned because I have an egg allergy. I can eat baked/cooked things that contain eggs but raw/lightly cooked eggs will ruin my whole day. Luckily I dont think I consumed enough for it to effect me. After all that they still charged us for the pancakes. I also think its worth mentioning that they dont have real maple syrup. I personally think this is a crime and unacceptable to serve breakfast without maple syrup in Canada! It shows a lack of care in regards to quality.

Good food for the price

Good burgers

Pleasant, fast, delicious! There is no better place to have peameal bacon & poached eggs, with rye toast, homefries & beans. I drink tea, but the boys coffee cups were never empty. Great start to any day at 8 a.m

Nice fluffy blueberry pancakes

Not near as good as the original Diamond grill Downtown

Awesome food good prices

Always excellent food and customer service

Food was good and portions are quite large. Will go again

Good food..good service...price, qualty and quantity is fair.

Good food great prices

Great food.... Even better service!!

Excellent atmosphere, Jay is awesome, food is fantastic. Best peameal Ive ever had!

Good environment! Like it.

Me and my girlfriend went here on our first date as a new couple. We are now married and look foundly on our lunch dates we had there. An old 50s and 60s styled diner. Friendly efficient staff. Lots to choose from. Glass coke bottles and shakes also. Great music and interior. Eat in or dine out. Good classic food for the whole family to enjoy. Thanks for the memories.

I love the breakfast here. I highly recommend the Pick 5. The pancakes and eggs are great. Service is fast and friendly.

The pick 5 breakfast menu is the best idea I have always wanted and should revolutionize breakfast menu in a perfect world lol. I always find at other places for the same price I am stuck with their breakfast combo and have to make some sacrifice as to the options I can choose, but here I can get eggs, bacon, potaote, beans, toast one day, and french toast, pancakes, sausage and fruit the next day. I have not been to the restaurant in a long time as I hate to say I found a hair one time. But that type of stuff happens it is a one-off from all the times I have been there. The cook is really nice and friendly and would fix any complaints I am sure.

Amazing ... best breakfast in durham.

Food always good service fast and extremely friendly going there for years hours in evening not always consistant

Step back in time in this traditional diner. Great owners and SUPER staff

Love the diamond grill great food great owner and staff

Good food, friendly staff!

Grand slam breakfast is great value and the food is awesome. Wish the homefries were deep fried but thats just my preference. Might ask for that next time.

Owner really nice and friendly man

Great place great food friendly atmosphere
