"Brotherco" is an unusual cafe without an owner, which is located in Seochon, nearby Gyeongbokgung Station. The place is like a free gallery and a self cafe, where you can drink and eat snacks for free from a snack bar in the room.
However, you have to put 5000 KRW into a red mailbox as a cultural fee to enjoy all of these in "Brotherco". 10% of the cultural fee are donated to children in need.
