Campus of Vienna's university... nice green place with some restaurants, beer brewery at Stiegl Ambulanz
nice aqua zoo in one of the flak-towers... great view from top platform
of course a must in Vienna a vine tavern... in Ottakring... not so crowded with tourists like the ones in Grinzing and Neustift
located in Urania observatory, with nice view on the danube channel... very central located next to Schwedenplatz
