Hey Europeans - can you help?

Hey gals -

I'm planning a 6-week trip to Europe in May, and I was wondering if any of you could give me any tips about gay-friendly places or gay bars in the cities! Where do you like to go, what's fun, what's not going to make me go broke?

My girlfriend and I are planning on hitting up Europride in Switzerland, but that's all we've found.

Any hints?

Thanks!
