Yeah, they're called nightclubs with outrageous prices for drinks, or juice bars. Been to a few myself. But somehow I doubt your idea of "a space where people dance without alcohol" involves loud rave-type music. Maybe you could clarify

Loud 'party' music? Yes. Rave music? Not necessarily.

Alright, I'm intrigued. What use case isn't filled by most nightclubs?

-Bouncers often compulsively search you in order to make sure you don't bring extra alcohol inside

-Prices are at a ridiculous premium, typically to profit from the artificial scarcity but also in order to discourage and punish drunken behavior

-Loud party music galore

What exactly is missing?
