We'll be visiting the Amana Colonies and environs this summer and would like to hear some opinions about the handful of German family style dinner houses in the area. We've read conflicting reviews of the various restaurants i.e. Ox Yoke Inn, Brick Haus and Colony Inn and would welcome any thoughts or suggestions. We're trying to find something akin to the wonderful places like Good n' Plenty or the Stoltzfus Farm Restaurant in the Lancaster area of Pennsylvania. Also...has anyone eaten at the Iowa River Power Restaurant in nearby Coralville? Thanks for your help!
