You can definitely find awesome food in places off the beaten path.
When I was a kid, we used to do a lot of road trips, including when we moved from one state to another. Even as an adult with a stabl living situation, I often travel Texas highways & back roads for business and pleasure, and occasionally even drive to New Orleans to visit family.
So I’ve found some interesting places to eat in some pretty small towns. There’s a restaurant on the TX/LA border that did great catfish, and offered a remarkable remoulade sauce instead of cocktail or tartar sauce, At a gas station in the middle of nowhere LA, they sold fritters made with crawfish, crab or shrimp so good we went back for seconds before we got too far away.
Between Dallas & Houston, there’s a family that owns gas station/restaurants on opposite sides of the same highway exit. They sell an array of fruit preserves, smoked meats, and snacks like bacon wrapped quail. We tell people to stop there and bring us stuff...and order stuff from their webrute.
On the interstate between Dallas an Austin or San Antonio, I’ve found Czech bakeries, southern-style bakeries, steakhouses, German, Austrian, and Hungarian dining halls that were as good and authentic as any I’ve been to in those countries...because they’re owned & operated by transplanted Europeans and their descendants.
