And the follow up comments on comments while looking for anything on
Vital Leaf Tea in San Francisco.

I was by there yesterday, the 19th. I agree with the comments on it
being smack on the end of tourist row in Chinatown, I found it because
I was tooling through on the bike and trying to find some tea while in
town.

I also agree with a bit of concern about the (well, some of the)
selection being in big glass jars; but then the tin they pulled my
puerh from was, er a tin. I'd think you'd almost _have_ to put the
wares on display like that to compliment the business model of having
'looky-loos' and the odd passerby stop in and get interested.

As for the actual tea I am only able to report I purchased a small
amount of some wood bridge puerh loose leaf, I've only had the one cup
this morning (without proper technique, I am sure). I find it earthy
and complex and worth investigating in a better manner, following the
instructions the sales staff provided.
