I asked around for a Dim Sum recommendation, and people pointed to this place though referred to it by different names. Their business card says "Grand Harmony." It is grand -- it's large, fancier looking than the small restaurants, and clean. My foreign cousins thought the flowers in the bathroom were very fancy.
They have Dim Sum from carts, typical Dim Sum style. Everything was very good -- lots of delicious shrimp dishes, and also beef and pork. The Jasmine tea is very good. I was a little surprised that they don't have as many sweet things as other Dim Sum places (not that others have a lot, but we were only even offered 1 sweet item, which was nevertheless a delicious coconut cream bun). Fun place. Clean. Right in the heart of Chinatown action on Mott Street.
