I went there for dim sum yesterday. It was good, possibly better than Fortune. Cheaper, too.
It's significantly smaller than Fortune, about the size of Oriental East. It's furnished sort of like a senior citizen's community center, except with hanging ducks and pork. And tanks of seafood.
Overall the food was highly varied and tasty. There were a lot of things I hadn't seen anywhere else in DC. A plate of stir fried leed flowers? chives? [the vegetable from Full Kee but without the flowers] mixed with mushrooms, bean sprouts, ginger, squid, and pork particularly stood out. Strangely, I didn't see a couple basic things -- shumai & harkow -- until I was walking out the door, stuffed. There was so much other good stuff to eat, I didn't care.
The roast duck was better than anywhere else I've tried locally.
The carts had an irregular circulation pattern, so it was hard to get some stuff, or it would be cool by the time it got to you. Or there would be no carts for a period and then a flood of them. The circulation was getting better toward the end of the meal.
They also had some stuff -- wide rice noodles, hot tofu with ginger -- that didn't appear on the carts, which you could get by asking the guys in the suits. The suit guys were very friendly and attentive, moreso than average.
The other notable thing was that the staff seemed very English oriented. At other places, the cart ladies tend to chatter in Chinese, and then switch to English if it's clear you're lost. Here they generally started out with English, and everyone seemed to have strong English skills.
