Gralehaus (Lexington, Ky.) • Grind Burger Kitchen (Louisville, Ky.) • The Original Dinerant (Portland, Ore.)This trip, Guy Fieri's grabbin' everything from brunch to burgers! In Lexington's Highlands neighborhood, an old-house-turned-bed-and-breakfast-lunch-spot crankin' out southern comfort, like fried bologna sandos. Then on to Lexington's NuLu area, where an eclectic joint's cookin' up pork belly Cubans and killer veggie burgers. And in Portland, a diner/restaurant mashup dishin' out chicken and waffles with a kick and decadent donut sliders.
