From Hearts Coffee & Bakery Seongdong-gu Office Branch is a cafe near the Seongdong-gu Office and Wangsimni gopchang alley that serves cafe mocha, cake, bread, and croffles. The cafe mocha comes hot or iced, and the salt bread is served warm if you ask for it to be heated. The two-story space has a high ceiling and a large table where meetings can be held, and it stays open until 11 p.m. The first floor is spacious but the second floor is small, and the bus stop in front of the store can make the area crowded.
