Starbucks Hongdae Airport Railroad Station Branch is a Starbucks in Seoul that serves coffee, yogurt, and cake, located near Hongdae Station and the Airport Railroad Station. The basic Americano is not strongly acidic, and drinks are picked up on the first floor. The store has three floors, using the basement and the first and second floors, and it is quiet until 3 p.m. while it gets crowded from around 4 p.m. The restroom is only on the second floor and is small, so a line forms when there are many people.
