Taco John's is out of (of all places) Wyoming originally in around 1957 or so. As we who have read the blurb on the bag know.
So it is only in the Northern Midwest . Surprised they aren't in Illinois.
The main thing with Taco Johns is the meat is better quality and you get more of it compared to Taco Bell. There is actually some vitamins/minerals remaining in the meat and you feel good afterwards. Unlike most fast food outfits. But you'll still need a tums or two an hour later.
