Seongsu Japanese restaurant for butter-grilled steak katsu: Gyuen Dang
Gyuen Dang Seongsu Main Branch is a Japanese restaurant near Seongsu Station in Seongdong, Seoul. I grilled sirloin steak katsu with butter on a personal mini brazier, and loved the cozy setting and attentive service. Verdict: Gyuen Dang is a date-night meal I would happily return for.
