Cafe 309 is a bakery cafe in Jingwan-dong, Eunpyeong-gu, at the foot of Bukhansan in Seoul. It serves coffee and bread, with flat white and Yirgacheffe drip coffee among the options. Tables are spread across three floors, each floor has a restroom, and on weekdays there is piano playing at set times. The rooftop on the third floor looks out over Bukhansan, and because the bread selection and quantity are limited, most items sell out for those who arrive late.
