Open since the spring of 2007, this terrific Spree-riverfront steak house is still one of the city’s see-and-be-seen hot spots. (No surprise, given the résumés of its founders, nightclub impresario Boris Radczun and gallerist/art collector Stephan Landwehr.) With low ceilings, deep chaises, and red-lamped lighting, the interior functions as a set for chicly dressed filmmakers, stylists, and the odd European celebrity—all of whom come to feast on platters of grass-fed Argentine beef, French entrecôte, and Australian Wagyu in a variety of sauces (port-wine, aioli, spicy habañero). The seafood’s no slouch here, either; noncarnivorous types can get their fix with plates of grilled dorade, king crab legs, and super-fresh oysters. A forewarning: service here is notoriously flaky.
