Starbucks Seolleung Donsin Building R is a coffee shop that combines a Reserve bar with a core store, and it sits closest to Seolleung Station Exit 10. Reserve drinks and siphon coffee are served, and classic milk tea can also be ordered. The Reserve-only seats require ordering a Reserve drink to use, and although the store is busy on weekday afternoons, many customers take out, so seats open up quickly. The seating layout is inconvenient and most of the seats are uncomfortable.
