Went to SF on Rosemead and Valley yesterday. Food was great. One of my dining companions from Shanghai said this is "real" Chinese food.
They take orders similar to sushi with the ittle checklist. I really prefer the carts that circulate at other places. They have a nice picture menu so there are no surprises about whats coming but still I like the immediate gratification of the cart.
Pros : Great food, lunch can be ordered in addition to Dim Sum
Cons: No carts so no previews.
