Located in Seochon Village on the west side of Gyeongbokgung, the Palace of Shining Happiness, Daeo bookstore is the oldest in Seoul. It is named after a married couple, Cho Dae-sik and Kwon Oh-name, who founded it back in the 1950s. Nowadays, it is a second-hand bookstore as well as a little café. It is open in the afternoons and evenings. I had an iced yuzu and lemon tea for 6,500 won (£4). Cash only.
