For all fans of sausage sandwiches, you must try a Leberkäse! It's the absolute best Viennese street food. It kind of reminds me of spam, but less salty. Had the Mushroom Truffle Leberkäse with sweet mustard. It was so amazing! The Classic was great too. 👌 I was in a search of a place offering a quick bite & this place totally hit the spot. For under €4, its a cheap thrill you won't want to miss.
