On this trip down memory lane, Guy Fieri's sampling all sorts of savory eats. First up on St. Simons Island, Ga., Guy's catching up on all things BBQ -- from brisket chili to a pastrami Rueben. Then, he's headed across the country to Los Angeles, where an Italian deli is churning out chicken parm, and a sandwich shop just down the street is loading fried food inside their supersized subs.
