There is a place in northern Indiana, an amish community, called
Das Dutchman Essenhaus, it's an amish restaurant, and they serve "family" style. Their food is just about the best-home cooking (amish) I've ever had in my life.
But to be honest, I don't see how it's really any different than the kind of food my mom and some of my aunts prepared years ago.
I think they use the amish theme just to bring in more business. Although they really don't have a reason to have to TRY and bring in more business, they would have it anyway.
