Hollys Coffee

Hollys Gangnam Station Branch sells coffee and cake and sits directly in front of Gangnam Station Exit 11. It serves drinks including vanilla delight and iced americano, with seating spread across the first floor and the basement level. Orders placed at the kiosk trigger a Kakao notification to your phone when the menu is ready, and the store is open 24 hours. On Friday, Saturday and Sunday evenings it gets crowded and loud, and there are few power outlets.
