I no longer travel very often, but in decades past....
I was an impoverished GI newly to West Germany. A fellow trooper from TN and I wanted to get off base so we went to Mainz, just a short train ride from where we were stationed in Dexheim. We got there with no civvies, just our fatigues. After leaving the train station we saw an information kiosk and asked the lady within about accommodations. She proceeded to tell us about conventions and such and then suggested that we go here, then there and find the hotel/winehaus Lorenz. She told us to look for a tiny sign designating it. We found it and went inside. The proprietor seemed agitated/excited and filled our dinner orders after seating us in the wine cellar/restaurant. After eating our meals and the place filled up with college students, remember we were still wearing our military fatigues, the piano player began playing US military tunes, Battle Hymn of the Republic and such. But by that time we were feeling absolutely no pain from the fantastic Rhine wine. The proprietor, the instigator of all of this, came over and explained how his dad had been a member of the Resistance in France during WW2 and we were the first GIs that he recognized that he could thank for what our country had done. He came over with a bottle of cognac and we toasted to the USA and to us, and GOD knows what else. He left the bottle with us and told us to finish it, which we did. It was a wonderful night that I will absolutely never forget. Once in a lifetime.
I have no idea if it's still there, but it's near the cathedral in Mainz, and it's in the old Roman section not far from the cathedral. I could, to this day, probably walk to it from the Bahnhof. If it still exists, and I know the building and wine cellars do, it might be worth seeking out. Unfortunately, my experience and yours won't be the same. Ours was once in a lifetime and never to be repeated. When we came to the next morning we went across the cobblestone street and bought civvies so that we could blend in. But for that one night it was fantastic. I'd love to know if the hotel/winehouse Lorenz still exists for the college students of Mainz.
After that I had 2 years to partake but mostly from "GI accommodations" in liberated towns. Garmisch/Partinchirchen, and Berchesgaden (sp?). But I stayed in the SS barracks. Marble stairs and such and fantastic meals. Also a B&B outside of Innsbruck, in Igles, and above the olympic ski jump, nice B&B, but there were many in that town. I'm talking '70-'73. Wow, what a jolt back to the past! But it's something that I'll never forget. I quite liked Igles, Austria and the B&B. Do that in winter.
