Groto is a cafe in Dohwa-dong, Mapo-gu, Seoul, located underground in Gongdeok and focused on hand-drip coffee. It offers six drip coffee options along with an almond latte and distinctive objet cups. The underground space uses dark tones and stone decorations to evoke a cave, and the seating is spaced widely apart. The restroom requires walking up stairs, so care is needed.
