Lets go to a Teahouse!
It's a digital free zone (step outside if you need to check your phone, etc), it's a peaceful atmosphere ;)
They specialize in Pu-erh teas, but the other ones are good too (I've also tried some of the green and oolong teas). You get enough leaves to brew many cups, until the leaves are spent (you get a thermos full of hot water and can get it refilled).
They also serve some vegan snacks. Bring cash to pay.
Probably a good idea to carpool - I can take some people, and would leave San Jose around noon.
