Packed with Chinese patrons and a haunt with local students, Ruby Rouge is fantastic.
The wait staff is very efficient and the carts keep coming without long waits, although I'd really like more dim-sum carts and less of the fried/heavy stuff.
Try their dou-hua (or do-fu-fa, they'll understand), I think it is to die for. They got me so hooked on it I get cravings every week now.
I think it is slightly more expensive than Kam-Fung in the neighborhood, but I recommend trying it. I found Ruby to be less hectic and better organized.
