Donghaeru is an old Chinese restaurant on a side alley off the main road in Wangsimni, serving jjajangmyeon, jjamppong, and tangsuyuk. It offers fried meat and tangsuyuk, and the tangsuyuk comes with crispy meat and sauce served together. Portions of dishes and meals are large, and basic side dishes such as danmuji, chunjang, and onion are self-served. Because it sits deep in a narrow street away from the busy area, it is hard to find the first time.
