The name promises just what it implies: Upon entrance, guests regard the opulent fireplace and grand piano in the lobby. But it’s in the luxuriously appointed rooms and suites that they will feel like true royalty. The restaurant, helmed by head chef Martin Fauster, offers seasonal fare with views over Karlsplatz. He’s held on to his Michelin star for over ten years...no wonder, with tantalizing dishes like salt-crusted sea bass or Breton lobster with fennel-tapioca.
