In California, there are some restaurants attached to gas stations. There are Arby's and Subways that connect to the little convenient snack stuff of some pump stations.
I do not recall those food chains claiming to be the best in town though. I have yet to get food from one of these places. They are all different and the locals claim that some of the best bbq in town is at the gas station down the street.
This weirds me out. It just doesn't seem like the cleanest of options for dinner. No offense. I'll pass for now, thanks!
