What are you looking to do, and where in the city are you staying? Vienna isn't a very large city, but it has a lot of distinct options.
There's a couple of pubs that regularly have Spurs on TV, and one that a small supporters group meets at if you are here when there is a match being played.
Will spend most hours at the Juridicum and will be staying close to that as well. Looking for something (anything) exciting to look at in the daytime, not too far away.
