As it is custom for every year, we are celebrating the Bitcoin Pizza Day. https://en.bitcoin.it/wiki/Laszlo_Hanyecz
We're going to hang out and sit down at the widely popular Gärtnerplatz (it looks like a pizza too, doesn't it?) and order pizza, using bitcoins of course.
This is BYOB, although we'll probably offer some beers, mate and other beverages, as long as stocks last. Especially bring blankets and other stuff you might need!
If you have questions, suggestions, or special wishes, please comment!
