Hogam Haejang is a hangover soup restaurant at the entrance of Hyeondae Coa in the Cheongnyangni food alley in Seoul, serving sop bone haejang-guk and naejang-tang. The naejang-tang contains seonji, beef tripe, and yang, and the seji muchim is mixed with buchu and a sweet-and-sour seasoning. The soup broth is warm, spicy, and served in large portions. Few staff are on hand, so you have to call them yourself when you need something.
