We have a similar chain here in central North Carolina since the 50s, the Char-Grill. If you get a good one, it's the best hamburger you've ever eaten. There's no seating (except for a metal picnic bench bolted to the ground right outside), and it has an odd ordering concept where you fill out a form and stick it through a slot to order. You can see the guys cooking your burgers or whatever right through the glass (it's right up front and the only room in the place besides the storeroom and bathroom). And it consistently gets incredibly high sanitation ratings, like 99.9%. There have been several years where they've actually gotten 100%, which is unheard-of. (Unlike a Burger King I used to go to, which had a D rating the last time I went.) There are always people outside the Char-Grill at night freezing their asses off waiting for their burgers to be cooked.
