It’s hard to believe the outer walls of this bustling Berlin restaurant and wine bar are actually made of glass – floor to ceiling shelves are filled with some of the 900 wines from around Europe, including some 400 reislings, which they offer. Striking reds cast a syrupy hue across the downstairs bar, dotted with crisp laid tables and more casual bar stools. But the real action takes place on the second floor in the well-designed nouvelle cuisine restaurant. Chef Marco Müller experiments with a ‘global aroma cuisine’, creating fresh and exciting dishes with clever use of spices and herbs. The clean cut and stylish space tends to attract a hip and affluent Mitte crowd. Rutz is considered a hotspot for an early evening glass of wine and light snack as after-workers arrive in droves to loosen their ties and relax. Full bodied and full of life – the best address for wine connoisseurs in Berlin.
