Jeongkwangsu Coffee House Jeongdong is a coffee shop on Jeongdong-gil, across from Ewha Girls' High School and in front of Jeongdong Church. It serves coffee of the day and single-origin beans such as Guatemala and Kenya, along with simple baked goods. The shop opens early in the morning, and the first and second floors look out onto the street. The stairs up to the second floor are narrow and steep, and the seating is cramped.
