So we tried this place a few years ago when visiting Montreal. After that disaster of a dinner at Kueng Kee in Montreal Chinatown the other night, I was skeptical on Chinese food here. The low ratings of Ucan also made me more reluctant but after walking down St Catherine street towards the far end where UCAN is located and not finding anything appealing, we ended up at Ucan and jumped in with eyes closed.
To our delight, the food was hot, fresh, flavorful and the service was decent. The three dishes ordered came out steaming hot and ample portions. I can wholeheartedly say that the food here is worth 4 stars. Seating is comfy and the place is not seated back to back tables where you could whack other patrons in the ribs reaching for your dish. I would highly recommend this place for a meal and did not experience any of the issues as reported by the other Yelpers with -2 star ratings.
