Sigol Gamasot Tojong Sundaeguk is a Korean restaurant in Seoul that serves sundaeguk and bone hangover soup. The sundaeguk special contains plenty of thinly sliced meat and offal, and the broth is rich. The bone hangover soup is boiled for a long time so the meat separates easily from the bone, and it cannot be ordered on Sundays. Takeout orders do not come with kkakdugi.
