Alter Simpl is a fantastic place, one of my favourite bars in Munich.
Not at all Schicki Micki and friendly staff IIRC.
Unfortunately I can't make it, but I hope you get a big turn out

If you've never been before, btw, then don't give up if the front bit is packed - there's a room up the back also. Head down the little narrow bit on the right. A lot of people don't realise this first time they go in.
