Oats Coffee Gwanghwamun is an open-plan cafe on the second floor of the KT Gwanghwamun West Building in Jongno-gu, Seoul, selling coffee and bread. Its signature Einspanner combines chewy cream with strong coffee, and a matcha spanner is also available. Views take in Sejong-daero, Gwanghwamun, Sejong Center and the Admiral Yi Sun-sin statue. Seating is hard to find around weekday lunchtime, and the coffee and bread are disappointing.
