Restaurant: Impossible XV (8)

Robert Irvine travels to Muncie, Ind., where the rundown Madison Street Retro Diner is in dire straits. Owner Rita Watkins is in charge of the place, but her health is failing, and her daughter, Melissa, can't seem to step up to the plate and take over. Robert has two days to give Melissa the tools and confidence she needs or this home-style, American restaurant has no chance of survival.
