Insadong Kalguksu is a small restaurant in the basement of the Hana Building at the entrance of Insadong, Seoul, serving kalguksu and memil bibimmyeon. The kalguksu comes in large portions, and the spicy kalguksu is served hot and pungent. On weekdays, breakfast is available from 7 a.m., and asking for a larger portion gets you more at no extra charge. There are not many tables, so it gets crowded at lunch.
