What is the name of the diner Roseanne and Jackie co-own?

The sisters opened "The Lanford Lunch Box," but everyone just called it "The Lunch Box." The restaurant's name came from Roseanne's youngest son (at the time and depending on continuity) D.J. Conner, and the space was an old pizza joint. The Lunch Box primarily sold loose meat sandwiches, which Jackie discovered while on the road. The place became the show's go-to location for workplace comedy, giving us endless scenes of the sisters bickering behind the counter while serving what were essentially sadder versions of both hamburgers and sloppy joes. Despite the questionable menu concept, The Lunch Box became successful to support the families, though that success sometimes fluctuated wildly depending on whatever scheme the Conner family was cooking up.
