What a fantastic view as it's right on the Rhine. Ok, that's 3 1/2 stars all by itself...face it it's all about the experience; add to that comfortable outdoor seating...another 1/2 star. Food and drink are self serve (well, you stand in line, order drinks and food, and pay), but the staff brings the food and clears the table...normally I'd subtract a star, but here it makes sense, at least on weekdays when the crowds aren't prevalent. Finally the food...2 stars. It's bistro fare, though done nicely. My wife had the dish of the day: carpaccio with potato asparagus salad and I had the bratwurst with potato asparagus salad. My bratwurst was cooked to perfection, and the special house mustard was spot on. For drinks we both had Riesling from local wineries...hers was a 2018 Georg Breuer dry Riesling, and mine was a 2019 Schloss Vollrads Riesling mild (somewhat sweet).
