While Nobelhart & Schmutzig established the sustainable food movement in Berlin, Otto is the newer spot that everyone is really excited about. There are just a few dishes to try - as well as a predominantly natural wine list - but ingredients like trout, wild herbs, and leafy greens come from the nearby forest area of Brandenburg, with things like pickled veggies and mangalitsa ham made in-house. The restaurant has just 19 seats crammed close together and it’s only open Friday through Monday, so book a table in advance.
