I'm back from my Portland adventure. Have to say I was disappointed in Tao of Tea. We went to the one on Belmont, and waited 5 minutes before ordering, and then at least 15 before getting our tea, which I found wasn't that great. We waited another 15 minutes and they never did bring the check, we had to go ask for it.
But, at the Japanese Garden (which is amazing), there was teaware on display/for sale by teaware artisans and I picked up a cup by Reid Ozaki.
