Hotel Sacher Wien

Just opposite the Opera House, Hotel Sacher is old-world opulence at its best (antique furniture, oil paintings, silk wall coverings). The first-floor Café Sacher has a glassed-in terrace that opens up during the summer, and the spa uses La Prairie products exclusively. The hotel's three colorful culinary spaces include the Rote (red) Bar, where the famed Sacher torte was supposedly invented. But just as decadent is the Blau (blue) Bar, with its deep-blue velvet couches and matching walls.
