Hongdukkae Kalguksu is a neighborhood restaurant in Seoul that serves kalguksu (knife-cut noodles). Its clear, spicy broth is paired with soft but chewy noodles, and the prices are relatively affordable. Eolkeuni kalguksu can be ordered for one person and is served directly in a bowl rather than boiled like a hot pot. Seating is available on the second floor, and geotjeori is served with the meal.
