I highly recommend this restaurant since you're going to be in the general area.

Der Dutchman Restaurant of Walnut Creek, Ohio

Not sure what your time line is, but they have a beautiful Inn right next door. Check out the Carlisle Inn from the ad. (Usually they are all booked up during the Fall Colors season, but that hasn't started yet).

It's a really a beautiful rural area, and the restaurant sits on top of a big hill that looks out over the surrounding farms.
