Brunch, Bologna and Burgers

This trip, Guy Fieri's grabbing everything from brunch to burgers! In Louisville, Ky., a breakfast-lunch spot crankin' out southern comfort, like lamb grits and fried bologna. Then, an eclectic burger joint cooking up a pork belly Cuban and killer veggie burger. And in Portland, Ore., a diner-restaurant mashup dishin' out decadent donut sliders and chicken and waffles with a kick.
