What they say

"Fresh Seafood, Excellent Service"


The seafood, like their other location, is excellent and fresh. It's a much larger and more modern than the Lawrence location. The service was attentive without being too intrusive. We started with oysters, a couple of appetizers and just shared one main course. Will need to come back to try the other main courses! The menu is pretty extensive and not overly over-priced. Definitely recommend this place for anyone loving fresh seafood without wanting to pay outrageous prices!

"Just as good as the Lawrence location"


The Markham location was newer and closer to me. The place is much spacious, better I have found the seafood is even more fresh.. Had a one time not as good food experience at Lawrence. I've been this location a couple times now and food is fresh every single time.

"Hidden gem for seafood - high quality seafood at a reasonable price"


Entertained some business guests and they suggested Diana's. I had never come across it before - seems like everyone else knows about it as anyone I speak to rave's about it. They have great seafood dishes - everything very fresh. Service is good, wine selection is nice. I would describe it as a great value for seafood. I found the prices very reasonable for such high quality seafood - at the lower end of fine dining pricing.

"Yummy yummy!"


Celebrating our 32nd wedding anniversary, we decided to go to our favourite restaurant. Oysters are fresh as usual. When Daniel, the manager, found out it's our anniversary, he brought over their new soup for us to taste. Food always come out perfectly cooked. Grilled calamari is a must order. Daniel told us they will have a new Menu coming out soon. Looking forward to it for our X'mas entertainment soon.

"Had no idea this great restaurant was hidden away in Markham!


Wow! amazing food and lovely atmosphere. Great service as well. What a lovely restaurant. Had the crab cakes to start and the lobster roll sandwich for lunch and they were both excellent. My dining companions had the greek salad which looked awesome! and the lobster bisque as well as the tuna tartar and oyster sandwich. Have a wide variety of seafood on the menu to choose from. Highly recommend this restaurant!
