Iseunghak Donkkaseu Main Branch is a restaurant on the second floor next to Dongju Girls' High School in Nampo-dong, Busan, serving Western-style donkkaseu. It offers basic donkkaseu and cheese donkkaseu with a sweet sauce, and a soup comes out before the meal. The soup can be refilled once, and side dishes include danmuji, salad, kimchi, macaroni, and jalapeños. Collecting ten coupons after meals earns one bowl of basic donkkaseu, and a wait forms on weekends and weekday lunchtimes.
