I'm afraid E'town isn't really seen as a culinary destination. To be just a little more optimistic, though, the Stone Hearth has been around for many years and is at least locally owned and operated: Maybe something like John E's in Louisville?http://www.stonehearthetown.com/
I think there are also a few taqueria-style Mexican spots and some mom n pop Chinese, if either of those options sound preferable to the chains.
Also, is the Whistle Stop in Glendale, Ky., back in business? It's not far cross-country from E'town.
Enjoy your visit!
