Yonggung is a Chinese restaurant in Busan serving old-style Korean jjajangmyeon and tangsuyuk. It also serves ganjjajang and chadol jjampong. Jaengban jjajang and several types of jjampong are also available, and the dishes are prepared quickly. The jjajangmyeon is lightly seasoned and greasy, making it less satisfying than the jjampong.
