Sushi Kuni is a sushi restaurant that serves sushi, sashimi, and udon, located inside the Pyeong-dong apartment complex near Seodaemun Station in Seoul. The set includes sushi, Nagasaki udon, basic soup, and salad. The sushi comes with warm, moist rice, and the Nagasaki udon broth is on the spicy side. The space is small, so it gets crowded and a line forms when customers gather.
