This is about as traditional as Viennese street food goes, the humble Vienna sausage. The Vienna sausages from Vienna are nothing like we get at home. They are not the mass-produced slightly suspect sausages we think of. Rather they are top-quality.
You can find them on almost any street corner, usually served sliced with (not on) a roll, with a little mustard or tomato sauce on the side. They are great value and perfect for filling the lunch-time gap.
