Gwanbuk is a Korean restaurant in the Cheongjin-dong alley near Jonggak Station that serves sundae guk with soybean soup added. Gwanbuk sundae guk comes with a set meal that includes pork jowl suyuk alongside the creamy, light broth. In the evening, customers crowd in, so the dining room can get loud and packed. Orders are sometimes taken incorrectly, and the call bell does not work.
