Satoshi Spirits is a demonstration Bitcoin-only website that was built using the software I developed called Sovereign Stack. It emulates a classy Bitcoin bourbon-type joint.
I'm hoping a bar or brewery will take me up on a Bitcoin-only website so us Bitcoiners can actually have somewhere to spend our Bitcoin! I know this is a controversial point for some people, but me personally, I get a wild thrill up my leg every time a Lightning transaction goes through. Just saying.
