After reading many posts I decided to try out Yank Sing on Stevenson during my visit to SF. I have only eaten dimsum in the US, but I have eaten at Eilte and many random places in los angeles and new york. And Yank Sing was disappointingly mediocre. The selection was average - really all I saw was the typical hargow, pork bao, fried shrimp stuff- they served this scallop thing with DONKATSU sauce, and they charged 2 bucks a head for some plain old tea. We got 4 things - so little because we decided to go somewhere else - and it was 35 bucks.
Maybe I should have re-evaluated when I saw there were no Chinese, not even Asian, people there. Even going to Jing Fong in New York, which puts copious amounts of MSG in everything, is a much more fun and interesting experience than Yang Sing eating. The drab SF downtown backdrop made it worse. I believe going to colorful Chinatown would have been more enjoyable, considering that the atmosphere is livelier, the tea free, the flavors the same, and the bill half of Yank Sing's.
