The Black Queen is a club privè at Treviso, in the Veneto, and entry is by membership card — a card to get at the pleasure, as it puts it. Discretion, cleanliness and respect for privacy are the three things it names as fundamental, and it admits members and over-18s only.

Inside there are several situations to join or not, as you choose: a dance area, somewhere to drink in company, and other rooms that are more intimate and more private. Smoking is confined to the club's own smoking room.
