Snookums came across this site, which caters to the diner who (in part):

Passes by the familiar, bland comfort of the Red Lobsters, Olive Gardens and Golden Arches that have taken over suburbia, insisting on driving a few minutes or hours further - knowing that somewhere down the road is a barbecue pit, a truck stop, a diner, a drive-in. a greasy spoon that may well become the highlight of the journey.

Well worth the time to browse around on the site. It could be a bit better organized, but all in all a good-natured (if somewhat filling) homage to The Greasy Spoon.
