DJ Oskar Melzer and nightlife impresarios David and James Ardinast have cemented their credentials as restaurateurs with Stanley Diamond, a fine-dining restaurant in Frankfurt’s libertarian central station district. Intriguingly named after a New York Mafioso associate, the venue was designed by local architects Hollin and Radoske and designer Paul Bauer, who used exotic materials such as green Indian marble and rose-pink concrete to achieve textural contrast and warmth. German furniture design studio e15 contributed luxuriously proportioned chairs to the space, while a natural stone installation by Swiss artist Nouria Behloul masquerades as a reception counter. The food has a touch of the sentimental about it, with regional specialties like plaice Finkenwerder (plaice fried with bacon) served alongside comforting classics such as Osso Bucco and the owners’ acclaimed pastrami from their first restaurant, Maxie Eisen.
