OZ, short for Ohne Zwang ('no pressure'), is a day bar, lounge and café in Ansfelden, 25 minutes by public transport from Linz main station. It describes itself as a discreet, stylish setting for special encounters and a meeting point of the scene, open to everyone whether lesbian, gay, straight or transgender, where guests can explore their fantasies in a relaxed atmosphere. Besides the bar there are private lounges showing films for undisturbed moments.

The house rules are firm: respect for one another, and no always means no. Prostitution and drugs are banned, photos and videos of other guests are not allowed, and what happens inside stays inside. Entry is from 18, a day ticket includes a simple drink, and there is on-site parking with video-monitored access.
