A correction is in order.
The restuarant on Rosanne was not inspired by Maid-Rites. It was inspired by a local eatery in Ottumwa, Iowa called “Canteen Lunch in the Alley” (or as the locals call it, “The Canteen”).

Tom Arnold, Rosanne’s one-time husband, grew up in Ottumwa, where The Canteen is a beloved landmark. She and Tom were known to eat there during the run of the show. The layout and furnishings of the TV restaraunt are nearly identical to The Canteen.
To the uninitiated, their loose-meat hamburgers (also called Canteens) are similar to Maid-Rites, but Ottumwans would vehemently argue Maid-Rites are inferior to the local sandwich. Ex-pat Ottumwans have them shipped across country, and usually make pilgrimages to the Canteen whenever they are in town.
Maid-Rites are tasty and popular around Iowa, and for this former Ottumwan, are the next best thing to home.
