On-premise / off-premise
Also: on premises, off premises, open club / closed club
The two basic types of LifeStyle venue. On-premise clubs provide spaces to play on site; off-premise clubs are social-only, with any play happening elsewhere afterward.
On-premise and off-premise describe whether sexual activity is permitted at the venue itself. An on-premise club has private and semi-private rooms where people who connect may play on site. An off-premise club is purely social — a place to dance, mingle, and meet — where any play happens later at a home or hotel. Local liquor-licensing and zoning laws often dictate which model a given club can legally run, which is why the split exists at all.
The distinction shapes how an evening works. At an off-premise venue the whole event is socialising and building connections, with the understanding that play is a separate, later step you arrange yourself. At an on-premise venue the social floor and the play spaces coexist, and house rules govern movement between them. Neither is more 'serious' — many couples prefer the clearer boundary of off-premise, others like the all-in-one nature of on-premise.
For newcomers, knowing which kind of venue you're attending sets expectations correctly: an off-premise club is a particularly low-pressure place to start, since nothing physical is even on offer on site, while an on-premise club rewards having a clear agreement with your partner about what, if anything, you're open to that night.
