Bern for 1 night - Any recommendations?!

Hello Bern InterNations Members, I will be visiting Bern for a night on June 17th (I've a meeting there on the 18th). I will be travelling alone so I thought I'd ask you folks for recommendations for where to go out for the evening AND/OR would anybody like to meet up? (any GT foreseen?) Thx ! Cheers! Luis F.
P.S.- In fact as I'm a frequent traveller I discovered that IN is the greatest thing for those who have an hectic prof. live . Besides my IN home town folks I had already a great experience in Moscow and Warsaw with IN Folks too. IN communities are not virtual like the other social nets it's a real stuff that helps to develop real pleasurable network. Really a great thing I may insist!!!
