Din Tai Fung I believe is the best Chinese Restaurant in the Central Embassy Shopping Mall. It is actually a brand from Singapore.
This was something special shared with two friends who came from England - really quite emotional and I can't really recall the quality of the food and whether it was expensive or not.
Recommended for the dumplings...
