Yao is a traditional tea house in the alleys of Gamcheon Culture Village in Busan, serving tea, tea ware, and small desserts. Green tea, matcha, and pu-erh are brewed in front of guests and served with yanggaeng or other desserts. The owner explains how to brew the tea, and paintings drawn by the owner and tea tools are on display. It sits one step in from the main road, so the entrance is not easy to see.
