I've come to this dim sum restaurant for about three years since I moved to the GTA. In many ways the quality of GTA Chinese Dim Sum is tops in Eastern Canada followed by Montreal. Alternately, you'd have to go out west.
This is a no frills dim sum place and the food does not disappoint. As in my previous reviews on dim sum the litmus test consists of three staples that a restaurant must not, cannot, and should not fail. The holy trinity is Har Gow (shrimp dumpling), Sui Mai (pork dumpling), and Sticky Rice in lotus leaf.
In short, Rol San passes with flying colours as the flavours are on the mark as is the texture.
Keep in mind this is your typical plastic over the table, no nonsense Chinese restaurant. If that turns you off then the place is not for you. Otherwise, enjoy, enjoy, enjoy.
Rating 4/5 (minus one for the condition of the rest room).
