We were delighted when we chose the Steigenberger Hotel in an overnight stop at Frankfurt Airport because of this restaurant we read about. It was described as an authentic frankfurter restaurant so this would differentiate it from the usual international cafe other airport hotels offer. They delivered more. There were basically 4 dining tracks you could select from the extensive menu. The buffet at 33€ is not spectacular so unless you are in a hurry, we'd skip it. The second is a complete goose meal. We weren't enamoured with so much goose in one go so we went on. The fish dishes comprised species like pikes, while genuinely local, aren't as enticing unless one has severest diet restriction against meats. So we went for the Wiener Schnitzel which is fried golden brown and juicy inside. It was simply the best schnitzel we have had in 30 years! It came with a trip to the salad bar and grilled potatoes redolent with bacon. At ~25€, it was by far the best choice. We washed it down with some George Debouef Beaujolais nouveau which was just released. If you must overnight at Franfurt airport, this is definitely the place to eat.
