Gonggan Dabansa Seonyu is a small cafe in a converted hanok, located between Dangsan Station Exit 4 and Yanghwa Hangang Park and Seonyudo Park. It serves three kinds of milk tea — rooibos, assam and earl grey — along with basque cheesecake and egg tarts. A rabbit tunnel leading to the Han River is visible as soon as you step out of the shop, and on a holiday afternoon around 3:30 pm the cheesecake and egg tarts sold out. The space is not large and there are not many tables.
