Sushi Gongbang in Haengun-dong is a sushi restaurant serving sushi and sashimi, a 5- to 8-minute walk from Exit 8 of Seoul National University Station. Each piece of sushi uses hoe, and the basic udon has a deep broth with crispy toppings. The dining room has few tables, so a wait can form at peak hours, and many customers order takeout. The amount of rice in the sushi is on the small side.
