Bars in Main Shopping Area
Just as there are cafés around every corner, there are also bars. Some cafés even turn into bars once the sun starts to set. Enjoy home and imported beers, draft and bottle, or a range of wines or cocktails.
Bars can be super classy or super low key. You can generally judge the bar by its cover to get a feel of how "dressy or not" you should be. But for the most part, you shouldn't worry too much. Vienna isn't an expensive place to drink, but it isn't cheap either, so make sure you have enough cash on you.
