We stopped in here on a Saturday of a long weekend so we knew it would be busy. We waited for a table for about 15 minutes or so. The host was very efficient if not a little curt.
Once we were seated and placed our order it wasn't long before the fod arrived--and it was delish! We tried just about every Maki roll, along with fried tofu (fantastic), tempura and the usual appies. They missed a few of choices but they promptly brought them over as soon as we told them.
One thing to keep in mind is that the all you eat sushi part deal is over at 3 (final orders in by 250). We were seated at 220 and we didn't have much time to put a second order in. I felt rushed because if this and wished we could have had more time to order and eat.
One more annoyance was the fact that he brought our dessert, three bowls of ice cream, to the table before all of our sushi had arrived. This forced us to eat it in the middle of our meal before it melted. How hard would it have been to wait and dish it later?
Bottom line food was delish but service was lacking but I wouldn't really expect much more from an all you can eat sushi place on one of the busiest streets in Montreal. Make sure you give yourself enough time to eat as much as you like without feeling rushed.
