I had to try the restaurant in Zum Golden Oechselen after reading about it in the hotel reviewers' comments. I was going to stay there but walking distance from railway station a little too far with bulky luggage so stayed somewhere closet (in another review!).
The restaurant is veru upmarket in fitout, menu quite extensive and relatively high prices to match. But the food is good. I wanted something different to wurst & schnitzel andgot it with a coq au vin but done in Franconian style with Franconian red wine, cabbage & potato dumplings. Huge serve and very tasty. Glad I didn't order an entree & too full for desert. If you want some fine dining in Aschaffenburg you can find it in an unlikely Gastätte. Bon appetit!
