Vienna is this gay man's paradise. But mainly from April-October. The colder months aren't as fun gay-wise. But are manageable none the less. Most of the gay estabishments concentrate in the Kettenbruckengasse and Pilgramgasse areas off the U4 subway line.

Yes, Vienna is conservative, like Munich. But they are not intolerant. However, they are very well-mannered in public. So loud or outlandish behavior is not recommended. They are somewhat private and reserved in nature. And just because they speak German, they really aren't like the Germans. And in Vienna, very few look German. Moreover, Austrians like to "bury things under the rug" in a "if I can't see it, it doesn't exist" kind of way. So don't bring up WW2 in a light conversation. There is a saying: Austrians did a fantastic job of convincing the world that Hitler was German, and Mozart was Austrian.
