We had a dinner at Ryu Westmount. The food was delicious. Wine list is not that great but nice list to chose from. But our waiter was unprofessional, rude and ignorant. We asked to change the waiter but he kept coming back to our table. We had to stop ordering, paid and left. Unacceptable. If the name on bill was correct, his name is Chau. If you ever get him, believe me in your own interest to replace him from the beginning. Not sure how management can allow such unprofessional people to work in service in this kind of restaurant. Shame.
