I came across a coffee shop + ukulele store in LA a number of years ago called U-Space.
I'd like to build something like that one day.
In semi/actual-retirement, I like the idea of running a 3rd space for people to just drop in and get to know their community. A plain old coffee shop won't do that because you'd have no reason to interact with strangers. But having some casual side-activity like drop-in judo lessons or water tasting competition or whatever, just might!
Kinda like revscene, but in person, and with coffee.
There's a run-down corner convenience store in my neighborhood that I'm eyeing. One day I'll buy it and ruthlessly tear it to the ground. I'll replace it with a two-storey concrete & steel structure and lots of wood paneling. Floor to ceiling glass. Maybe something like R Ki Coffee Lab in Richmond:
