If you like fashion then this is the place to be. The label was founded in 2005 by Nando and Silvia, two spanish designers. I like this place because I love the wool coats and the patterns they create. They support local industry and that is a top of the top for me.
It's a small bookshop to be stuck forever. Here you can find the most beautiful collection of art/photography/architecture/fashion/food books and magazines, not to count it's just a walk distance to diverse galleries around the neighborhood.
A very nice little second-hand bookstore, including a shelve with international books in French, English, and Spanish too. Always nice people to meet and a great selection of art and cook books, for affordable prices.
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.
