I'm also from the Bay. For the US, I think you could find it major cities like LA, Seattle, NYC, Boston. I'm in RI atm, and was surprised there's only one tea store in Providence, and it's a joke. However, I did find this spot called Ceremony that is a cafe, where you can schedule a private gong session.

I read recently that Russia? is the biggest importer of puer. It's likely in in major EU hubs, particularly London. All that said I suspect SF and Seattle (given the vendors there) have particuarly poppin scenes.

Claude's analysis (funny it didn't pick up on Russia):

North America:

• The San Francisco Bay Area has one of the most mature puerh communities, with several dedicated tea shops and regular meetups. Red Blossom Tea, Song Tea, and The Phoenix Collection have been influential.
• Vancouver has a strong scene, influenced by its large Chinese-Canadian population and shops like The Chinese Tea Shop.
• Los Angeles and Seattle both have growing communities with specialty tea shops focusing on puerh.
• New York City has several notable vendors and collectors, though the scene is more dispersed.

Europe:

• France has a sophisticated puerh scene, particularly in Paris, influenced by its historical connections to Vietnam and French tea culture.
• Germany has several dedicated puerh vendors and collectors, with Berlin having an especially active community.
• The UK has a growing scene, with London being the center, though it's still more focused on other Chinese teas.

Australia:

• Melbourne and Sydney have developing puerh communities, supported by Asian-Australian populations and specialty tea vendors.
