Oliveyoung Seongsu Station Branch is a cosmetics store 30 meters from Exit 1 of Seongsu Station. The large store carries a range of beauty products, with self-checkout counters and a pickup service for payment. The Oliveyoung Lounge gives one free drink and one free cake per person, but the wait ran about two hours even on weekdays. Many tourists make the store hard to move through and cause inconvenience with payment and product guidance.
