This place is wonderful. I felt terrible for having lived in a tea-centered culture for so long and knowing so little about it. So one afternoon on a shopping trip I went into the store. The staff is fabulous, friendly, helpful, and passionate about tea. I learned a lot from them, and went back for a couple of tea making classes. Once you figure out what you like, you can start ordering for home delivery. This is really good if you live far out of the city and don't have a chance to get to Roppongi very often. I think it's also a good place to bring out of town visitors to learn more about tea.
