Wonjo Yangpyeong Haejangguk is a hangover soup restaurant near Seolleung Station in Seoul. Its yangpyeong haejangguk has a broth that pulls at the sour kimchi, and it also serves sundae guk, bugeo haejangguk, and ppyeo haejangguk. The shop is tidy and draws office workers at lunch, and the yangpyeong haejangguk has no strong smell and comes in a large portion. The taste is not that of authentic yangpyeong haejangguk.
