I've been to this restaurant several times, primarily when family from the U.S. comes to visit. It's been redesigned in the past couple of years as a less-formal venue (no tablecloths any more on either the enclosed or non-enclosed terrace, when we went in May...and August 2018); the food remains very good, and it's got a great selection of its own and neighboring areas' wines as well as wines from other countries. Seating will depend partly on dress -- when our party better attired in May, we got a window seat in the terrace with its view of the vineyards and the Rhine below; in the heat of August, when the group included a T-shirt-clad teenager and all of us men were in shorts, we were seated on the outside terrace close to the restaurant's interior window (though that also kept us out of the blazing sun) (things were complicated by a Rheingau Music Festival concert in the palace, so lots of tables were also reserved). We've had no issues at all with the staff, ever; it could be that a couple of us knowing German helped in that regard.More
