Have been going here for years. The owners are Taiwanese brothers, but they are not affiliated with the Ding Tai Fung in Taiwan, they just use their name.
The dumplings here are the best you can get outside of Taiwan, I would give it a 8 out of 10 when compared to the real stuff in Taiwan. The pork pot stickers are good, but sometimes I just don't think it's fully cooked as the pork seemed a bit too pink.
The hot pot is also one of our favorit, and you can ask them to refill the soup when you are almost done. Beef noodle is good too, but not as good as the one down the street. If you have a craving for dumplings, this is definitely the place to go.
