BF and I nipping over to Berlin for a quick 3 day trip in late December to see the Christmas market's etc, so just to save me searching the whole city and wasting my time whilst probably still missing out on where I SHOULD have gone at the start just wondering has anyone any quick tips for the typical "must see" type gay bars or clubs whilst we're there ?

I know there are plenty of hot bars and clubs catering for just about whatever you're into there but this trip what with it being Christmas and all I'm not so bothered about any hardcore stuff ( well on THIS trip perhaps - and thats "probably' not bothered until I get there I should say more like :-) - but no, for now just somewhere to go for a bit of crack whilst there and to perhaps enjoy the gay christmas atmosphere of Berlin for somewhere different - so any good tips guys ?
