Margaret "Maggie" Duval is Soraya Duval’s smart aleck mother and Marion's best friend. Maggie ran a business in town called Maggie's Tack and Feed. In Season 7, Maggie sells the diner to live in London with Soraya. Lou doesn't want to let anyone to turn Maggie's into a hotshot fast food joint so she ends up buying it. Many people hang out at Maggie's. Lou opened up a second Maggie's Tack and Feed in New York.
