Diana's Oyster Bar & Grill Markham

My buddy Ian and I were heading to the cottage through Toronto and we're looking for someplace interesting to eat. We found. Diana's Oyster Bar and boy are we glad we did. Been a minute since we've had such an amazing selection of raw oysters, the sauces and spices were delicious, the price was reasonable and we finished with a huge bowl of their delicious clam chowder. Service was excellent, great decor...Highly recommend you try it out.

Seafood stew is horrible, very little seafood in it and yet they charge me 40 bucks plus tax

I visited twice, for lunch and dinner. The oysters were fresh and delicious, and the lobster sandwich is also highly recommended.

it was empty during lunch but there was a wait during the weekend dinner hours.

You can enjoy oysters and wine while watching sports too！

Went here with the family to celebrate a birthday. Atmosphere is clean and well maintained. Servers were excellent and very helpful. Dinner took a bit longer but definitely did not disappoint. Caesar salad was a great starter. Enjoyed the shrimp and lobster tagliatelle which was creamy and rich. The number of shrimp and lobster pieces in the dish did not disappoint. It was a fantastic meal.

We had 150 oysters between the four of us, which was amazing. The server was very friendly and the dishes we shared were the seafood paella, calamari fry, special pasta.
The seafood paella was full of seafood and was really good. The calamari fry were the softest fry I've ever had.
It's a long way from home, but I would go back again!

Had a reservation at this restaurant on October 26th at 7:30pm for 8 people to celebrate my mother's milestone birthday. I initially recommended this restaurant to my family as I had a good previous experience...but after the poor service we received. I honestly don't think I'll be coming back. Issues we had with the service:

1. Our server was just a bad server. Didn't take all the orders at the same time even though most of us were ready to order. He missed a few people at the table and we had to flag him down.
2. When the server was telling us the specials, we asked what one of the types of fish were and he told us to "google it". And when asked for oyster recommendations, he didn't seem knowledgeable at all and wasn't really able to recommend anything with confidence.
3. Part of our order was missed and a couple items weren't brought to the table.
4. 2 people at our table didn't like their order because the food tasted bad. We relayed this information clearly to the server and sent the food back to the kitchen but the food was still charged on the bill and we had to ask a different server to fix it.
2. We brought a cake and gave the server a pack of 8 candles. When they brought the cake out for my mom they only put 3 candles on the cake. And when my sister asked for the rest of the 5 remaining candles to be returned to us, they never gave it.
3. Took forever to get the bill. By the end of the night we were only one of the last handful of tables, so I don't understand why it took so long. No one checked on us and we had to ask a bus person for the bill.

Overall for a bill that was over $1K with an 18% automatic service charge for a large party, it was in very poor taste to give us such an inexperienced server. This person definitely needs more training, or the business needs to hire better staff. Our server left at 9pm in the middle of the dinner rush which we found to be weird. The servers we had after were more pleasant. Most of the food was very good (aside from the 2 pasta dishes that were ordered). For a more upscale restaurant averaging at about $100+ per person, we definitely expected better service, more knowledgeable employees, and better attention to detail. We are very disappointed with this experience and are very hesitant to ever return.

The pasta dishes exceeded our expectations. The mussels were half-price on Monday at just $10—a fantastic deal. The oysters were fresh and delicious, adding to an overall great dining experience.

Kid-friendliness: Kid's meal is only $12 with a big potion and tasty pasta

So bad, if you have a birthday party, you must do a good job of marking it. Otherwise, you will bring the wrong things you prepared on the important day, and you will have to be sad all night. It is a very bad experience.

A lot of us are familiar with the name Diana seafood. We ordered fried calamari, oyster Rockefeller , Crab cakes , Ahi Tuna Tartare, Cesar Salad , Calm chowder for appetizer . I considered these appetizer acceptable! No one in the group wants wine or beverage and the waitress changed her face and look really upset! I am major surprised there is no training for such a popular restaurant . We finished with $600 for 6 adults and 2 kids but I will not be going back.
