Die besten Restaurants mit Eiscafe Essen in Mülheim an der Ruhr

Went there for the first time today. The location is simply fantastic. However, when ordering, you will be informed that payment can only be made in cash and only in advance. When I kindly pointed out to the waitress after using the toilet that there was no towel paper in either toilet, I was unkindly informed that the person in charge wouldn't come until 1:00 p.m. It was just 11:00 a.m. For us, this is absolutely a reason not to visit this restaurant again.
