Happy Hour is available from 4 pm to 6 pm, during which you can enjoy the best view of the Viennese skyline - on the 18th floor of the SO/Vienna - and a complimentary glass of bubbly and fries upon presentation of a valid accreditation pass. Please note that during periods of high demand, waiting times may occur if capacity is reached, and the offer may no longer be available once the venue has reached its maximum capacity for the day.
