Seedcube Changdong is a mixed-use office building in Changdong, Seoul, housing a hospital, restaurants, and cafes. Restaurant floors occupy the second and third floors, while Starbucks and Burger King are on the first floor, so meals and drinks can be handled within the single building. The building is newly constructed, so the interior is clean and cool in summer. The indoor layout and entrances are complex, making it difficult to find your way.
