Silla Jemyeon Lotte World Mall serves kalguksu and nakji kalguksu in Jamsil, Seoul. The kalnakji carries black pepper heat even at the regular spice level, and the gamjajeon comes as thin starch batter topped with potato slices. On weekend peak hours the wait runs up to an hour, so remote booking through Tableling is the better option. Leftover food cannot be packed for takeout.
