Rinas Seolleung, in Seoul's Gangnam-gu, sells sandwiches, salads, soups, juices, and coffee. It sits close to Seolleung Station, and customers choose items from a display case and pay at a kiosk. At lunchtime the shop fills with office workers and waits run long, so it is quieter around 2 p.m. The coffee amount is small for the mug size, and adding hot water requires a separate order.
