Guldaebak & Chogye Guksu in Seoul specializes in oyster and maesaengi dishes, serving gul gukbap, gul tteokguk, and gul dolsot yeongyangbap. In summer it serves chogye guksu with floating ice, black bean noodles, and maesaengi samgyetang. The gul gukbap contains a large amount of oysters and comes with kimchi and kkakdugi. The chogye guksu has a weak balance among the noodles, broth, and chicken.
