A place where I spend some time almost everyday is the Marheineke Markthalle on Bergmannstraße in Kreuzberg. It's just around the corner from where I live and a great place to buy fresh food and products from local farmers or all kinds of delicatessen from different countries. Many market stalls also sell freshly prepared food and it's always busy at lunchtime. For saturday mornings try the original french croissants.
Floating University Berlin is a self organized space and group, where practitioners from a wide range of backgrounds meet to collaborate, co-create and imaginatively work towards futures.
It defines itself as “A Natureculture learning site” investigating alternative narratives for urban development.
I am totally in love with this place!!!
