I was planning on doing a dim sum post but never got around to it. If you go to a good place, it is delicious. Here are some standard dim sum dishes. Pics from google.
Siu Mai (pork/mushroom dumpling)
Ha Gow (shrimp)
Cheung Fun (shrimp or beef inside, rice noodle outside)
Don't know the name for this one (I know my Chinese sucks) but it's bean curd on the outside and pork/mushroom on the inside, very delicious.
Dan Tat (standard dessert, custard egg tart)
I may post more later.
