I lived in Hanoi until recently and became very fond of the food, especially two dishes: Bun Cha and Cha Ca, which I haven't found in NYC. Does anyone know if you can find them here? (Note: I've tried the Cha Ca at An Choi and it was simply not the same. The fish is supposed to cook in front of you and you put it together yourself.) I've been missing them a lot!
