Beokbeok is a hamburger restaurant in an alley between Daehangno and the side gate of Sungkyunkwan University's Humanities and Social Sciences Campus in Seoul. The Double Beok uses a thick beef patty with cheese and pickles, served with jalapeños. A kiosk and waiting area are on the first floor, and three tables are on the second floor, where pickles and jalapeños are self-serve. The stairs to the second floor are narrow and the duplex ceiling is low, which is uncomfortable for tall people.
