Oben ('up') on top of the Hauptbücherei Wien, the rooftop terrace here provides a sweeping vista of Vienna to the south. Come for a coffee, Upper Austria–sourced organic juice, Viennese wine, Austrian beer, schnapps or cocktails with a view, or a good-value, two-course lunch (€7.50 to €9.80). Sunday brunch (€18.80) is extremely popular.
