I will often go for dim sum here. They use a traditional trolley service which is nice. However, the food quality isn't that great, but then again you're not paying too much for them -- $2 a dish.
Tip: if you go for dim sum in the afternoon (past 2:30pm), dishes are $1.80. Also, make sure you get the beef rice noodle (not a dim sum dish but a lunch dish which you can order during dimsum). It has an authentic wok taste!
