Hugging an idyllic canal in Neukölln, Griessmühle is a sprawling indoor-outdoor space with a funky garden strewn with tree houses, Trabis (GDR-era cars) and flower beds. The project by the ZMF artist collective woos attitude-free electro lovers with an events roster that includes not only parties and concerts but also a monthly flea market, movie nights and ping-pong parties.
