“In the sitcom Roseanne, Roseanne Connor’s restaurant, the Lanford Lunch Box, was based on the Canteen Lunch in the Alley, in central downtown Ottumwa, which has been a stopping point for Ottumwans since the 1920s. Many famous patrons have been seen eating a “Canteen”, a loose meat sandwich similar to a Maid-Rite.”
