I have been there couple times. Good quality and variety of sushi with very poor costumer service. We happened to miss couple of orders many times. Once we were 7 ppl and stand in line up for more than an hour on Saturday( which was crowded), which was unacceptable. When we ask to match two tables to fits us, they refrain to do so and tend to get two smaller group which were just arrived.
Simply, worst management and costumer service i have ever seen in montreal.
