Dim sum done well for pocket change. I always get the chicken feet and char shiu bao. In order to eat some delicious dim sum, you must be willing to make a few sacrifices.
On busy days, the servers will probably never be there to help you or even bring you water. You must be proactive and actually walk up to these guys. Expect a few scowls from the ladies pushing their carts. No one can be continuously cheerful pushing one of these things all morning. And when they do smile, you know it's gonna be a good day:)
Oh, and don't wait for your check at the table. Bring your little stamp card up front so they can ring you up. Otherwise, you could be there forever. Why give it 4 stars, you ask? Chinese restaurants are notorious for bad service. I'm grading on a curve.
