Qusrus Coffee is a small coffee shop in Seoul that sells coffee, tea, and cookies. It serves single-origin coffee, vanilla latte, lemon tea, and misutgaru, and roasts its own beans. The shop opens earlier than most cafes in the Singdang, Cheonggu, and Dongguk University Entrance area, which typically open after 9 a.m. It has professional equipment, and the space is small, so it does not suit those expecting wide seating.
