Osulloc Gimpo Airport Branch is a green tea and matcha drink cafe located at 112 Haneul-gil, Gangseo-gu, Seoul, encountered right after passing through airport security. It serves Sejak, matcha latte, and matcha cloud spanner, along with ice cream that blends green tea and milk flavors. Drinks come out quickly, and seating by the window looks out onto the runway and departing planes. It is used as a spot to rest briefly with matcha before boarding domestic flights.
