Taco John's, which might be the most flyover country thing about me, it's a chain that's huge in the rural Midwest but basically non-existent on the coasts. It's not all that common even in the large metros of the Midwest, none in Chicago, and the only ones in Minneapolis are in a downtown food court, there's a couple in the suburbs but kind of spread out in outer areas.
I remember Taco John's. In the 1970's the store in Little Canada MN fueled our late night games of Risk and Dungeons and Dragons. Beef burritos were my regular then. I don't think I've had one in decades though.
