This is an amazingly fun place to visit, try some good tea, and experience some interesting snacks. At heart, I'm a loose leaf tea person, and would have liked to see some more selections, otherwise I would have 5 star'd the place across the board.
Can honestly say, I stopped in just to see the place, then revisited both the shop and the restaurant each and every day I was in the Portland area. Even made the drive from Tacoma one day. The knowledge, friendliness, selection, tasty treats . . . this place is the whole package. If you can only visit one tea house in Portland . . . make either of the Tao of Tea places . . . and you won't leave without a wonderful experience.
