Der Weinlobbyist on Kolonnenstraße — sommelier Serhat Aktas, ranked among Germany's top 50, curates German and Austrian wines, every winemaker met in person on the estate.

What started as a wine bar has grown into a full wine restaurant, the kitchen running a bistro line built around the glass. The sparkling list is among the most talked-about in the city: roughly 70 German Schaumweine, from small single-vineyard cuvées to the larger houses. Aktas runs his own Lagen-Cup competitions, the bar pours stories alongside the glass. In summer the mediterranean courtyard opens — a hidden gem in the middle of the city.
