When you're planning your visit to Cantina, you could take municipal transportation to the stop Bahnhof Vilshofen (Niederbayern), which is the nearest stop at 537 meters distance to the restaurant, otherwise, there are parking lots 82 meters away at Bürg.
We might have the menu for Cantina from Vilshofen an der Donau in the photos. A menu might be further down.
