Heading down Highway 15 from Corning to Williamsport. Anything good along the way (or not too far off the route)?
Eddie's Restaurant in Mansfiled PA serves a great breakfast, and burgers are good too. It's truckstop style. On the NY border, in Lawrenceville, PA is Rotsell's Family Restaurant.
In Lindley, NY there is a bar called The Green Shingles, nice wood stove, good burgers. Not really kid friendly.
