Seongsu Yeonbang in Seongsu is a complex cultural space with a goods shop, bookstore, restaurant, and cafe. The first floor holds Ttinggul Store, the second Ark & Book, and the third Cheonsang Gaok, covering small-item shopping, meals, and coffee. Two buildings are linked by a bridge, with a courtyard garden, a first-floor terrace, and a cafe with an open ceiling on the third floor. The space is not large, so restaurant seating and walkways are narrow.
