The biggest rooftop café in western Austria is found the roof of the University of Business Studies. The modern architecture, with its generous use of glass and ingenious lighting, creates a pleasant, airy atmosphere. Customers can enjoy some excellent Italian coffee, a choice of light snacks and a wide selection of cold drinks while admiring the wonderful view of the city. Segafredo Sky attracts a fairly stylish crowd including many students. And don't worry if it's a little chilly outside: the rooftop has been fitted with dozens of heaters.
