RE: I 80 Restaurants
Here are three suggestions for I-80 in Pennsylvania:
Plylers is located in Brookville (Exit 78). When they were in the 1992 Roadfood, they were just a little place that specialized in pizza. Now they are a huge place with a full buffet. Other than the pizza, the food is ordinary, but you can usually get in and out quick and it sits right next to the highway.
Tom's Kitchen is located in Conyngham (Exit 256). It has been seven years since I have been there, but I really liked it. They serve three meals a day and have really good pies and ice cream sundaes. If my memory is correct, it is about 2 miles off of the interstate in town.
Family Diner is located in White Haven (Exit 273). This has been in the Roadfood books for a long time. I have only ever had breakfast here, but this place is really good. It is less than a mile off of the interstate in town.
I hope this helps!
