One blogger has taken this as a new hobby:
Al Hebert, a medical journalist who blogs at GasStationGourmet.com about his eating adventures, once ate Cornish hen prepared by a classically trained chef in a Chevron station. “The average person just fills up their tank, pays with a credit card and drives off,” Hebert said. “But if you just walk a few feet from the pump to the store, you might discover one of the best eating experiences of your life.”
Here's a video about a food truck that not only is a popup at one gas station, but is planning on being a permanent fixture there and at gas stations across the region.
