What they say

"The Best Seafood Restaurant"


Again, Diana's served up another fantastic lunch. This time we had fish and chips, homemade fries, homemade coleslaw and finishing with their homemade cheesecake. It was all fantastic. The service was excellent, too. Very friendly and good timing with service. What more can we ask for: excellent food, great service and very clean place. The ambiance is modern and comfortable. Thank you, Diana's! Makes my day.

"The Oysters Are Sooooo Good!"


All I have to say is deliciousness. The food is filled with so many flavours, we had oysters, crab cakes and shrimp pasta, and it was all so good! I would definitely come here again. The service was great, everyone was so nice and humble and always made sure we were ok. I am pleasantly pleased, I have 0 complaints about the restaurant. I will definitely be dining here again.

"Delectable Seafood!"


This is my second time here and noticed the consistent great customer service and delectable food from my first visit. There were 8 of us in our group and we were all very satisfied with each of our chosen appetizers and meals. I highly recommend the Shrimp and Lobster Tagliolini Pasta. The others enjoyed their abundant paella (easily shareable with 2 people), the famous oysters, veal scallopini with scallops and shrimps, etc. It was the right choice to celebrate a birthday. Our visit was on a Monday night after 7 pm and it was not too busy.

"Best Seafood In Town!"


Don't be thrown off by location, this is the ultimate seafood destination in our city! If you value quality and freshness, this is the place. Always large selection of top quality oysters and other seafood. Very popular, best to make a reservation.

Great Oysters


Considering how busy this restaurant is, they did a good job accommodating seating right away for my friend and I. The quality of the oysters were excellent and also very reasonably priced! We also tried their Paella rice which was excellent and the seafood was very fresh. I would recommend trying this restaurant if you enjoy seafood!
