We have been reliably informed that the Opernplatzfest is starting today, located unsurprisingly enough by the Alte Oper on Opernplatz. I believe it also winds its' way down the Freßgasse. Going on for about 10 days, there is a daily program of live brasilian samba and south american music with 2 stages in the evenings. There are obviously loads and loads of stalls and tents selling food and drink.
The music goes on till 22:00 and the tents continue to stay open after this.
I would suggest meeting from 20:00 tomorrow evening if possible to make the most of the live music and the atmosphere.
Not really sure where to meet though, we could maybe meet up at the Bull & Bear between 8 and 8.30pm and then wander down the Freßgass from there? alternatively latecomers can PM me for my mobile number (if you already don't have it) and then just call to find out where we are.

It looks pretty cool so hopefully see you there tomorrow evening!
