If you fancy a hearty walk through Viennas largest park, the Prater, make the sexy-sounding Lusthaus your destination. Located at the southern end of the Hauptallee (main avenue), the present Lusthaus (or pleasure pavillion) dates back to 1782 when it was renovated after serving as a hunting lodge to the Habsburgs. Today it is a rather stuffy café-restaurant catering for Sunday strollers. Check out the nearby Freudenau race course with its superb 19th century grandstand.
