This is reviewed as one of the best dim sum places in the city. After a number of attempts (failed) to get in at popular times I was able to be seated at a very off time (4-5 pm). The dimsum were freshly prepared for me (and everyone), so after you order there is a bit of a wait - of course it is worth it for the freshness. :)
I sampled 4 or 5 (way more than I could eat, but also good the next day) all fresh, tasty and even healthy (okay I only got the steamed ones). The stuffed mushrooms were especially tasty and a rather large serving, others were more typical dimsum size. A bit pricey at $3-5 per plate, but this is SF. There is also an extensive regular menu which I will have to return to sample.
