Hanoi Jageumseong is a Korean-Chinese restaurant serving jjajangmyeon, jjamppong, and tangsuyuk, located on the first floor of SKY72 in the My Dinh Gyeongnam Apartments in Hanoi. On Mondays at lunch, tangsuyuk is served as a complimentary dish, and jjajangmyeon is sometimes divided into separate portions. The wait after ordering is short, and the restaurant offers complimentary gunmandu or the owner personally asks about any shortcomings. The tangsuyuk has weak acidity in its sauce, which makes the flavor disappointing.
