Gwanghwamun sushi restaurant for solo dining: Elephant Sushi
Elephant Sushi Gwanghwamun is a sushi restaurant in Jongno, Seoul, connected to Exit 2 of Gwanghwamun Station. I had the Elephant B Set at a table for two on my own, with generously sized sushi, futomaki, and buckwheat soba. A satisfying meal when you want to try a little of many kinds of sushi.
