Dukki Tteokbokki Busandae Branch is a self-serve tteokbokki buffet near Pusan National University in Busan. You fill your own bowl with rice cakes, add-ins and sauce, boil it at the table, then move on to fried items, ramen and bokkeumbap. Each meal is limited to one hour and thirty minutes, and ramen and drinks are included without a separate charge. The room fills up at mealtimes, so a wait forms, and student groups can make it loud.
