I've heard that Japanese cuisine in Montreal isn't the best, but that's probably because those people haven't been here!
Get sashimi or nigiri!!! Freshest fish I've had and the plating is spectacular.
Get anything made with their housemade dashi. Their miso soup had such complexity and depth. Tempura was great, tempura sauce even better.
It's fairly new establishment so him and his staff put a lot of effort and care into the dishes they prepare. You see it, you can taste it. I was very pleasantly surprised that Montreal has a taste for the furusato. Keep it up and soon enough this place will flow in with customers.
