I eat at Yank Sing (Stevenson) probably 3 times a month because it is pretty much across the street from my office, but my current fave dim sum is Dragon Beaux. Unfortunately it is way up in the Richmond District. I like Palette, but if you are used to dim sum being a great, cheap lunch, be prepared for sticker shock. My last time there I had 3 items and my bill was $51 before taxes and tip.
