I spent a week in Bratislava years ago. I don't think there was anything remotely gay in the city at all back then (except perhaps a random male stripper in a restaurant, if that counts!).

We did go to Zilnia one night, where the friend of a friend had a bunch of guys over to his house. That was about it.

I did have a great week in Slovakia though.

Vienna, on the other hand, very pretty with lots of gay things to do. But the place just bored me to tears.
