This shiny top-floor lounge is a posh see-and-be-seen venue for Vienna's socially striving nouveaux riches. There is a wide range of yummy cocktails, a superb selection of exclusive spirits, as well as a decent kitchen and cafe. The location is unrivaled for its bird's-eye view of the pedestrian life on Kärntner Straße. The modern designer furnishings are tastefully put together and, under the right circumstances, can be a lot of fun, particularly when you remind yourself that the Steffl building was erected on the site of the (long-ago demolished) house where Mozart died. Sip your drink and take in the panoramic views over the Inner City.
