Tamna Sundaeguk Gamjatang is a restaurant in Mullaedong, Seoul, serving sundae, haejangguk, and gamjatang (pork bone and potato stew). It serves eolkeun haejangguk and gamjatang, whose broth is not strongly seasoned. The gamjatang contains two large bones and one small bone and comes with geotjeori kimchi. The mustard sauce is disappointing.
