Duffy Yongsan is a drinking spot with outdoor seating on Yongridan-gil in Yongsan-dong 3-ga, Yongsan-gu, Seoul, serving lemon beer and pasta. The lemon beer is tangy and clean, and the tuwumba penne pasta comes in a thick cream sauce. The owner, a DJ, plays the music himself, and there is a disco ball light, with a group room and full-venue rentals available. All seats are outdoor seating, so the weather affects the visit.
