Did NOT like this place at all.
Horrible service and horrible dim sum experience. Items like steamed buns, came out soggy, and hot food came out as cold food.
We didn't get served tea until we handed in the order form. Unfriendly waitress gave me the index finger multiple times when I try to get her attention.
Maybe Ambassador is great before, but based on personal experience.. I think it's more like lunch at the ghetto part of China Town.
