Great prices especially for the amount of food you get and the quality is outstanding. Best burger I've ever had and I can't wait to try the philly cheese steak sandwich. A 10/10 , We're lucky to have this place here.

I'm extremely dissatisfied with the quality of the food i recieved from here the poutine fries were soggy , the gravy still had unmixed chunks of powder and was made with the tiniest amount of marble cheese , my potatoes in my main course were not done and the bacon was soggy and underdone. Really upset over my experience here.

Kate and I love to get out and explore - looking for a new spot for a late lunch, we found "Diamond's Grill". In the South part of Oshawa it is in a small strip mall in the company of a great Polish Deli, Barber Shop, etc. We had "brunch" - Jay, the owner, took great care of us. Eggs, omelet, bacon, etc. and honestly, the best coffee we have had in a very long time; anywhere. This is a small family business that has been in this location for about 13 years after moving from closer to downtown Oshawa and originating at Coxwell and Queen, many years ago. I can't say enough good about the place - you can see the pride Jay has in his establishment. Their family is also very community minded - fundraising and supporting a number of different charities in the neighbourhood. Thanks so much Jay - we will see you again SOON❣️

If you’re looking for a place with good food & better people check out Diamond. Portions are huge, price is fair, & the people who run the place are the main reason to keep coming back. As you can see in the pictures, I recommend the French toast with fresh fruit!

We love having this little gem in out community! The diner has a fab retro feel, serves a great breakfast for a reasonable price and the owner Jay and waitress Andrea are amazing. They make you feel welcome, like family, and get to know their customers on a first-name basis. Bravo! We look forward to many more years at the best neighbourhood diner around!

Diamond’s is a classic diner! We stopped by for brunch for the first time and really enjoyed our stay. The food was delicious and the price was right; my eggs were cooked perfectly, and I would highly recommend the pancakes! The owner, Jay, is so kind, friendly, and he accommodated for my friend who has celiac. The atmosphere has your classic checkered floor, red vinyl seating, with 1950s pop icons on the walls, and music playing from a mini jukebox. We will definitely be going back! 👌

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.

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.

August 22, 2024

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

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.

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.

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.

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! :)

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.

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.

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

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.

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

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.

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.

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.

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.

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.

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.
