Ossi Kalguksu Dunsan is a kalguksu restaurant in Dunsan-dong, Daejeon. It serves mulchong kalguksu made with surf clams and pajeon, with spicy kimchi on the side. The restaurant is in the basement of an office building, so its sign is hard to spot from outside, and parking is available in the building or on nearby street spaces. The clams are few, and the kalguksu alone is not enough for an adult.
