Jangwon Kalguksu is a small noodle shop near Sejong University in Seoul that serves dak kalguksu and myeolchi kalguksu. The dak kalguksu uses a clear, light chicken broth with chewy noodles made in-house, served with spicy geotjeori kimchi. The shop closes when ingredients run out, sometimes as early as 3 p.m., and there can be a line during lunch hours. The kimchi jeon is on the greasy side.
