The restaurant’s name should clue you in: This is the place for Peking duck. Crisp-skinned, tender slices come ready to be wrapped in pancakes with hoisin sauce and scallions, and duck soup arrives with both legs bobbing in the broth. For variety’s sake, add some more wraps to the table. Labeled on the menu as “Chinese tortillas,” the six offerings include stir-fried sour cabbage and shredded pork with fried bean curd.
