Hotel Sacher is widely known for providing the scenery for much of The Third Man and, more importantly, for its famous Original Sacher-Torte chocolate cake. The hotel’s red clad doormen will usher you into the crisp, classic café, where you can enjoy a fresh slice. True, you can get so-called Sacher Torten at other cafés around town, but there’s nothing like tasting the original in its noble home.
