My sis (American) will be in D'dorf with about 50 high school (and 150 college) students in May and I wondered - beyond the obvious imbiss stands, bakeries, McDonald's - if there were any cheap restaurants in D'dorf who could handle groups of about 50, or smaller groups of around 10 people, without too much chaos. They will be staying in the Oberkassel area so anything around there would be preferred.

If you are interested, they are performing a concert at this venue on the 24th of May. http://www.st-antonius-oberkassel.de/index1.html

This is the concert they are performing. http://www.certaindawn.org/

Feel free to PM me or post here if you have any restaurant suggestions.

Thanks!
