The Exxon at the corner of FM 1179 and Boonville, which I have only recently seen, as shown here in a picture I took this February. It has been open since 1995 and has had several restaurants in it (a bit unusual for something not off of a major thoroughfare), since it has a kitchen and an eat-in area. "Fratello's Pizza Company" is the only one I've found at this address (3200 Boonville Road) but they also have their location as at the old Daylight Donuts space a bit west of here.
In late 2007, it became the home of Stover Boys, a hamburger-and-fries outlet that kind of had a "rural outlet, specials written on a chalkboard" feel to it that opened to much local acclaim. It was where Bryan-College Station was acquainted with Charles Stover and his restaurants.
Stover's restaurant was an instant success, and people would come out to this little gas station and fill up every available parking space. When it turned out that people would pass it by rather than fight for parking, it was clear that Stover's had outgrown itself and Stover Boys moved into an old restaurant pad in Westgate Shopping Center, clear on the other side of town. This was in 2008, and although it opened around early 2009, the Stover Boys signage still hangs at this Exxon, which also suggests how rarely new restaurants come in.
As of 2018, "Taqueria Poblano" operates in the space.
UPDATE 06-17-2023: I know I previously updated this to account for Taqueria Poblano but I wanted to clarify that beyond Fratello's (which was here and did move to the other Boonville address), Stover Boys, and Taqueria Poblano, the other place I found was "Deli Depot". The gas station opened in 1994.
