I had an amazing conversation at the tearoom, not with Roy, but with one of his head staff. She introduced me to pu-erh teas. This was long before pu-erhs had experienced their recent fame. I tasted several, at first surprised by the aroma and flavor but refraining from a hasty judgement to allow for finding the sweetness on my tongue in the aftertaste. I treasure that moment and memory. I was the only one in the tea room and had the pleasure of soaking in the slanted light, the clay teapots, the aroma and flavor of the pu-erhs, and the tutorial from the tea expert.
Alas, this tearoom has closed. But there are others in the San Fran/Berkeley area.
Roy Fong is one of our leading US experts in tea, especially Chinese teas. He's an interesting man - check out his bio.
A few years ago, Mom gave me a subscription to an ITC tea club. It was so much fun! I highly encourage it as a gift to your special tea lover. (It is pricey, tho there are options.) Here are additional resources for more info about the Imperial Tea Court:
