I want to hear your favorite Chinese dish

Many people are exposed to different kinds of Chinese food (Dim Sum, Chop Suey, Kung Pao Chicken, Baozi) and depending on where you are you have tasted different things and different styles. Some may enjoy hot flavors while others prefer the coastal seafood. For those who have traveled extensively in China you may have stumbled across something unforgetable. I would love to hear anything from your past experiences about what Chinese foods you especially enjoy.
