Where would you recommend for dim sum in St. Louis. I'm staying in Clayton, so some of the places on Olive near the Inner Belt or in that general vicinity would be preferable. A couple of years ago, I was reading enthusiastic posts about Wei Hong -- not so much lately. Is all of the dim sum in the area cart service, which I like, or do some utilize ordering from a menu? Please give me your advice and any don't-miss dishes -- my tastes in dim sum are pretty basic; I like shrimp in rice noodles, fried potstickers, and good shu mai. Finally, the place needs to be open for Sunday brunch.
