Sling could be a nice place to spend an evening but unfortunately a staff member 8a short middle-aged bartender) is often rude and impolite. He expects a tip for no service at all. That attitude do not exist neither in Eastern European Countries. Moreover, Sling is often visited by certain members of Balkan community; some of them are hustlers and thieves. So, if you keep away from this place, you will definitely save up some money. Moreover, Vienna can offer you much more. Feel free to check the Sling. I would be glad if I am wrong.

Cruising bar. Sling is clean and with shower facility and besides its open every day. Therefor one of Vienna's most loved gay cruisebars.
