I travel to Benningen, Germany (outside of Stuttgart) a couple of times a year to visit a client of mine and love to visit the Bootshaus Biergarten on the banks of the Neckar river in Marbach. I was there the end of May 2018 and the weather was spectacular. Had a few pints of beer and a gyro. The restaurant has mainly Greek dishes but you can also get sausages. There is a pedestrian bridge across the river so we were able to walk there from Benningen. Here is a link to their website with more info: http://www.bootshaus-marbach.de/
