Seongga Baegam Sundae sells sundae-guk and mixed suyuk on the first floor of Doosan We've near the Jongno-gu Office. You can order sundae only or meat only, and the special sundae-guk comes with a large amount of meat. A line forms at lunch, and chives and extra rice can be added for free. The broth is seasoned strongly by default, so it does not suit those who prefer a bland taste.
