Isohyeon Yangpyeong Haejangguk sits a 10-minute walk from Chungjeongno Station in Seoul and serves yangpyeong haejangguk, haenaetang, altang, and sonaejangtang. Seonji can be added to the haenaetang, and the broth is clean-tasting with generous portions of seonji and other ingredients. The kimchi and side dishes are good enough to ask for more. The haejangguk is on the salty side.
