Fast Food Restaurants in Museum Quarter Area
"Fast food" doesn't have the same meaning here as it does in other places. The food is still freshly prepared and rather healthy - you just don't have to wait long for it.
In general, the Viennese prefer to sit down and enjoy their meals. But in today's world, sometimes we simply just don't have time for that. But taking into consideration Austria's super strict food laws, "fast food" places are still good eating (and affordable), even if on the run.
