Chen

Chen is the owner and manager of the Szechuan Palace Chinese restaurant, played by James Hong. He was first seen in "The Dumpling Paradox" and later seen in "The Tangerine Factor". He comes from Sacramento.

Chen was present during Sheldon's conversation with Leonard and Raj when he was complaining about their food order and how they needed Howard with them in order for it to work correctly. Chen told them they could have no substitutions, reductions or eliminations. He also made references to the fact that Howard wasn't with them and described him as an annoying little man who thinks he can speak mandarin. He offered to bring them four dumplings but agreed he would purposely drop one on the floor as he was walking over to their table and that no one would have to know. After Sheldon told him he would know, Chen gave up and walked off in frustration muttering mandarin to himself.
