Miseonggak is a Chinese restaurant serving jjajangmyeon, samseon jjajangmyeon, Samseong jjampong, and tangsuyuk. It is located in a basement in front of Seoul Tax Office, and serves Samseong jjampong and samseon jjajangmyeon with plenty of seafood, along with crispy tangsuyuk; the jjajangmyeon and bokkeumbap have an old-style taste. The restaurant is full during lunch, accepts delivery orders, and offers dine-in service. Its location in a basement corner is a drawback.
