The restaurant is always great. I had the Bao buns for lunch, which were good. The peppers were a bit too spicy for me and I love spicy food. It would be good to offer a little bit of hot sauce in leiu or in addition to the fresh peppers.
Dim Sum House is by far the best dim sum restaurant in Philadelphia. It is not in Chinatown but still the best. Not just dim sum dishes but they serve very good regular dishes as well. The food is authentic. I've been eating here for the past two years and it never disappoints!
