Etiquette in a venue like this is mostly the same as etiquette anywhere: treat the staff well, do not ruin anyone else's evening, and do not do anything you would be embarrassed to explain the following morning. None of that needs a guide.
What does benefit from being stated is the handful of things specific to a club built around private salons, where the expectations differ from a normal bar in ways that are not obvious until somebody gets them wrong.
Other People's Salons
A private salon is a private room, and the entire point of it is that the group inside is not on display. Wandering into one that is not yours, standing in the entrance to look, or photographing across into one is the clearest breach of etiquette in a venue like this.
Discretion runs both ways. You get it in your salon because everyone extends it to everyone else's.
Phones and Photographs
Photographs of your own group are fine. Photographs that capture other guests, other salons or the performers are not, and this is taken seriously rather than treated as a technicality.
A significant number of guests are here precisely because the venue is discreet. Pointing a camera around the room undermines the thing they came for.
Staff, Performers and the Door
Ordinary courtesy toward staff, and the same toward performers, whose job does not include managing guests who have forgotten where the boundaries are. Physical contact with performers is not acceptable.
At the door, if you are refused for dress or condition, arguing has never once worked. Door staff apply the same rules to everyone and have no authority to make exceptions.
Frequently asked questions
Can I take photographs?
Of your own group, yes. Photographs capturing other guests, other salons or performers are not permitted and the policy is enforced.
Can we look into another salon?
No. Private salons are private rooms and the discretion you receive in yours depends on everyone extending it to everyone else's.
What is the expectation toward performers?
Courtesy and distance. Physical contact with performers is not acceptable, and staff will intervene.
Is tipping expected?
It is appreciated rather than required, as is generally the case in Poland. Around ten percent is a common gesture for good service.
What if we are refused at the door?
The decision is final. Door staff apply the same criteria to everyone and cannot make exceptions, so arguing does not help. Almost all refusals relate to dress, age or condition.
