We stop at one of the best rated ice cream parlours in nearly every city we visit. Our friends in Potsdam advised us to try Eismanufaktur. We definitely recommend it too now :) Some special flavours: blackcurrant, thyme, mango, avocado or ginger and some classic: chocolate, lemon, vanilla and lots of others. We had a tasting of 15 different types and they all tasted top. Very central - go and try it!
