Junggukgwan is a Chinese restaurant near Namdaemun Market in Seoul that serves jjajangmyeon, jjamppong, and tangsuyuk. The tangsuyuk is chewy, and the jjajangmyeon comes out with a plain taste. The dining area is in the basement, and the narrow entrance can feel cramped when entering. The toilet is up a steep staircase next to the kitchen, which makes it inconvenient to use.
