Jongno Jin Nakji Jongno Branch is an octopus restaurant on Songhae-gil in Tapgol Park that serves san nakji cheolpan bokkeum and jeongol. The san nakji cheolpan bokkeum comes in mild, medium, and regular spice levels, and after the meal you can add dangmyeon or bokkeum bap. Staff boil the ingredients on a large griddle and trim the octopus as it cooks. At lunch on weekdays and weekends customers crowd in, so it is better to reserve before going.
