Yeonhwasan is a Chinese restaurant in Seoul that serves jjamppong, jjajangmyeon, and tangsuyuk. It also offers kongjjajang and naengjjamppong, and the tangsuyuk comes as a set. The jjamppong and tangsuyuk portions are generous, and each dish is cooked to order. The space is small with only a few tables, so it is not suited to group dining.
