Jangsu Seolleongtang is an old restaurant in Nonhyeon-dong that serves seolleongtang, dakgomtang, and ugeojiguk. The seolleongtang comes with generous meat, and the kimchi stands out; the dakgomtang broth is also rich. It has a first floor and a basement room, and there can be a wait at weekday lunchtime. The space is small, so arriving late at lunch means no seats.
