Nammun Tobang is an old restaurant inside Namdaemun Market in Seoul that serves Gyeongsang-style chueotang and sulfur-smoked duck. The smoked duck is eaten wrapped in chives and perilla leaf over boiling broth, with noodles added to the broth afterward. At lunch, Namdaemun shoppers and office workers crowd in for the chueotang, and in the evening the restaurant serves smoked duck. Service has been disappointing since the move.
