We eat here at least twice a month.
There are two things that set this place apart from most other dim sum restaurants in America, never mind just in Phoenix.
1. A chef who loves to bake. The head chef, Sam, is constantly baking up really delicious specials. These are typically sweets/desserts and they are awesome. He will come out to the tables on a busy weekend with a hot baking sheet full of pastries. If he offers, by all means, take some!
2. Extremely accommodating service. We take all of of friends there and that includes some very picky eaters, as well as kids. I've never seen any restaurant go to such lengths to make sure everybody is happy, including making all kinds of off-menu items to satisfy the pickiest eaters.
Bottom line, it rocks!
