Yeosin Jokbal serves jokbal and makguksu near Gasan Digital Complex Station in Geumcheon-gu, Seoul. The jokbal has a savory skin and tender, chewy meat. After 6 p.m. tables are mostly full, and on Fridays at 8 p.m. the front legs sell out. The room is small and crowded, and the noise makes conversation difficult.
