Challang is a rooftop bar in Mullae-dong that serves drinks and anju, with outdoor seating on the roof. Its signature dish, sundoritang, is a boneless dakbokkeumtang topped with fried sundae and kkwari peppers, and it also serves altang and seoksoe bulgogi. The venue has a first-floor space and rooftop tables, and on nice weekdays a wait forms. The food tends not to fill you up.
