Skip McDonald's and find true American cuisine where the eating is delicious and the price is right. The Roadfood website, see Tightwad Travel Links on the right, says, Roadfood is, “...non-franchised, sleeves-up food made by cooks, bakers, pitmasters, and sandwich-makers who are America's culinary folk artists. Roadfood is almost always informal and inexpensive; and the best Roadfood restaurants are colorful places enjoyed by locals (and savvy travelers) for their character as well as their menu.”
Membership is free and the Internet site's search function allows you to find all the Roadfood restaurants according to city, state, food item, keyword, and/or restaurant type. The 67 restaurant types are varied with everything from Asian-- deli, grocery store, small town cafe, tea room--to vegetarian. Before your trip, consult the lists for choices. When you get back home, add your favorites to the website reviews.
