If your looking for authentic Shanghai style dim sum, this is the place. It's as good, if not better, than restaurants I've been to in Shanghai.
The pork dumplings with soup have a thin dough and very tasty broth inside. They are light and fresh, allowing you to eat a lot of them.
The spicy wonton soup has a great combination of spices and a generous portion of bite size wontons.
The pork bun has a soft but not overly thick bun, allowing for a healthy amount of pork mixture.
The prices are more than others in the area, but the restaurant is clean and modern and the food is probably the best dim sum in Markham and maybe even GTA.
