Cheonghaeru is a Chinese restaurant in the Jang-anpyeong alleys of Seongdong-gu, Seoul, serving dishes such as tangsuyuk and jjajangmyeon. It operated on Toegye-ro for four to five years before continuing at this location for more than thirty years. One person runs the kitchen alone, so food tends to come out slowly. The set menus are small in portion.
