Always fast here - came here around 6 for dinner and there was a line. We were the 6th party or so, but got seated in 5miniutes. It's one of the bigger restaurants in Chinatown and some people are willing to share tables, so the turnover is pretty fast.
Anyways, you can always count on it for some comfort foods - congee, noodles, fried rice, rice with BBQ dishes. Cheap and good.
