ummm... you live in washington right? No idea.
BUT..... If she wants to take the trip...
The Japanese Garden in Portland, by the zoo and across from the Rose Garden has tea ceremoneys. I think you have to go there and make a reservation or appointment to see one of them though.. because they dont do them everyday, they only do them so may times a month or something. Maybe only once a month, im not sure. It's been a while, but I know they have them there.. ^_^;;; Sorry i know nothing from washington.
