Anyone know what the regulations are for bringing your own booze to non-bar type venues?

I remember back in the day you could bring a bottle into the Reptilian Lounge. Is this still the case in town?

You probably can bring beer, it just depends on the venue's rules. I know a few restaurants in town that don't have beer and wine licenses and they will let you bring a bottle of wine or beer for dinner.

I'd suggest a flask (or a few flasks) full of MacGreggor, the use of psychedelics instead, or drinking your fill in the parking lot and then stumbling into the venue.
