Service is bad, food is slow, and the nigiri sushi didn't taste much because it was practically all rice. I go there with friends when we are really hungry and want to stuff ourselves, but if one wants to enjoy actual sushi, there are many other places in Montreal.
On the other hand, the Korean BBQ they have upstairs is alright, you just have to pay some extra bucks for it (you can still have sushi with the BBQ). The service is mediocre, and they do not allow you to change the grilling plate once it gets charcoaled (unlike most Korean BBQ places).
