Cheolttuk Somori-jip 철뚝소머리집

The sign is so small that first-timers often circle this old house in a Jumunjin residential lane twice before finding the door. The name comes from the railway embankment (cheolttuk) of a line that once ran from Gangneung to Wonsan during the Japanese colonial era. Only one dish is served: Hanwoo ox-head soup with rice, a clean yet rich broth with no gamey edge and plenty of meat, usually on the table about two minutes after ordering. The aged kimchi on the side is deeply fermented, and the shop closes early once ingredients run out.
