Dukki in Seoul is a tteokbokki restaurant where customers eat instant tteokbokki, fried food, rice, and ramyeon buffet-style. Diners choose their own rice cakes, noodles, vegetables, eggs, and sauces to adjust the tteokbokki flavor, with unlimited ice cream and coffee included. Since April 2023 the hours have been extended to midnight, and the store is located underground. Many students and families visit, so the store is crowded with long waits and no place to wait.
