I went to check out King Hua for dim sum today. It's located next to the Alhambra Costco. Previous restaurants at that location have not been very successful. We know a few of the waiters, and it's true--the dim sum chef from Sea Harbour has now gone to King Hua. If you have noticed, the dim sum quality at Sea Harbour has gone done lately.
The dim sum was very, very good at King Hua, which confirms the chef change. Every was top quality. The service was pretty good also.
It's definitely the new place to go to dim sum, although the location is not too convenient.
