This is a good place for Dim Sum, just at the edge of the Montreal China Town. Although the placement inside a mall is not the most scenic or engaging, the food is good and the atmosphere is appropriate for a Dim Sum place. The dishes tend towards the greasy, but that isn't so unusual for Dim Sim.
Several people have compared this restaurant to ones elsewhere; I've had Dim Sum in Shanghai a few times, and for me this place compares well. A more detailed comparison with a specific restaurant versus a city or country is silly since Shanghai, for example, has both good places and awful ones, and it's a subjective issue. What I really want to find it a good authentic Chinese steamed bun (xiaolongbao) restaurant in Montreal (something like Din Tai Fung).
