I have been searching far and wide for a place in Toronto with a conveyor belt sushi bar. So far, I have only discovered Fune, in the heart of downtown.
The sushi bar here is not a conveyor belt, but rather a chain of floating boats rotating in an infinite loop. Same idea. A variety of sushi roll pieces, sashimi, and other things pass you by. You simply pick what you want from the boats--the price per dish is based on the colour and pattern of the dish.
The food is okay, but mainly it is a very fun and esoteric dining experience, which can get expensive quickly if you are not paying attention to what you are picking. There is also a menu if you prefer a traditional table experience.
