‼Go-to AYCE in the Niagara Region!!‼ Big Tuna has consistently been at the top of my list when it comes to AYCE and buffet-style restaurants. The food is always amazing, with great service and ambiance. The price is also, so far, the cheapest for AYCE in Niagara Region. I try other places, but I always end up coming back again and again. Pros: ▪ The tataki, especially the beef and salmon, is. out of this world! ▪ The sashimi is always so fresh. ▪ The curry pumpkin soup is top-notch. You rarely see places nail this soup. ▪ The short ribs are delightful. You can taste the time and effort put into the marination. ▪ Their house dressing is one of a kind. It could definitely compete with other dressings if bottled and sold in the market. And honestly, so many more. The list would go on and on if I wrote down all the menu items. ▪ They’re also always very accommodating of my dietary requirements every time. ▪ Of course, not to mention the ample amount of free parking. Cons: ▪You will definitely exceed your daily calorie limit. (Visit on cheat days! )

My family and I love going here. We ordered a large variety of dishes (on an tablet but we space out items) and they arrive fast, fresh, and hot. The young server we've had several times is sweet, thoughtful, and attentive. Quality of service is the best we've ever had in St. Catharines since moving here in May 2025. Our two children (2 and 4) love the variety of food and the portion sizes are perfect. Best AYCE dessert selections too!

First time trying sushi at a restaurant. Tried a variety of the sushi and meat options as well as a number of appetizers. Aside from one of the dumplings which just wasn’t to my taste I found everything I had to be amazing. Quality food, great tasting. Relaxed atmosphere, friendly service. Would definitely like to try it again.
