世界樹茶房 World Tree

World Tree is a cafe in Osaka where you can try a range of Chinese teas and buy loose leaves. The selection includes sheng pu-erh, jin bu huan, and rare white teas, served with pineapple cake, mooncakes, and sesame balls. The owner studied tea in China and explains each tea and how to brew it, and the menu also describes the teas. The list is long enough that some names will be new to you.
