Galchi Haejangguk is a hairtail soup restaurant on the main road behind Gyeongdong Market in Seoul. It serves spicy hairtail haejangguk, braised hairtail, grilled hairtail, and accompanying side dishes. Haejangguk and baekban can be eaten together, and the restaurant is near Gyeongdong Market’s herbal medicine street. The soup has hairtail’s distinctive fishy taste and does not suit diners who dislike fishy smells.
