Grainboundary Jongno is a cafe in the back alleys of Jongno 3-ga that focuses on crumbles and cookies. It offers a range of desserts centered on crumbles and cookies, with many options for people who do not drink coffee. The cafe uses three floors, from basement level 1 to the second floor, so the interior is large with many seats. It sits tucked in a corner, making it hard to find.
