Grit Coffee Lab is a neighborhood cafe in Cheongnyong-dong, Gwanak-gu, Seoul, selling hand-drip coffee, lattes, and sandwiches. Customers can choose between nutty and acidic beans, and the cafe brews drip and machine coffee from beans it roasts itself. Seating is located down on the basement level, and that space is quiet. The first-floor shop is very small and uncomfortable to sit in.
