Of course, if you want to shoot for 'Classic Americana', you may try Cracker Barrel. CB is a combination restaurant/store that serves southernish dishes and has cool old-timey American things on the walls like 1900's advertisements for this new-fangled thing called "detergent".
I double QotC's opinion on Cracker Barrel. And they are *almost everywhere* (according to their map, "more than 530 locations in 41 States"), except in California, Oregon, Washington, Nevada, Wyoming, Maine, Vermont, Hawaii, and Alaska. The states that have more CBs are on the East Coast. Here's the website:
