The shop is Cha Zhi Lin at 45 Temple Street. It's an odd place. It won't win any design awards. It's contemporary looking, missing the charm that the older tea houses have. The hook is the staff and the quality of the teas. The two young women (who always seem to be there) are delightful and very knowledgeable. Try the Great Red Robe (min bei oolong). They also sell wonderful tea sets.
