OK, I have to say it. If you want the WOW effect and looking for a place to impress a guest, you can´t go wrong with Herz und Niere. Although it specialises in gourmet fusion meet dishes, they made a specially tailored vegetarian menu for myself, which I found it to be sublime creation of tastes and aromas. The service was impeccable, the prices were a bit high for Berlin standards ( we opted for 5 course meal each plus a bottle of wine and payed over 250 Euros), but it totally deserves their Michelin recommendation, which we all know is not easy to get. Location is on a quiet street in Kreuzberg, cosy room, a slight acoustical problem, being too loud. I would suggest that one puts some sound-isolation materials on the walls or beneath the chairs in order to stop the loudness. Other then this :FABULOUS!
