The owner and chef, Peter, is afraid to make changes for fear of disturbing his late father's original design and menu. Robert has to flex some serious muscle to drag Peter into the present and keep this restaurant from going under.

When Chef Robert Irvine pulls off the highway to visit Denos I-76, a diner in Keenesburg, Colo., he finds the owner, Darlene, abandoned by her employees and working herself into the ground.
