Directors such as Lars von Trier and Peter Brook inspired owner Walid El Sheikh to create a dramatic setting. 434 square metres of space, spread over several floors and surrounded by midnight blue curtains, plus a 30-metre long bar - it's a setting that's almost obligatory. And then there's the location, overlooking the Kunsthalle, the renowned Hans Mayer Gallery and the Deutsche Oper. There have been occasions when part of the opera house orchestra has crossed Heinrich-Heine-Allee for a live performance.
