Season 2

Guy Fieri works ’round the clock, enjoying great food at some amazing joints that serve customers all day, every day: a 24/7 diner in San Diego that is flying in fresh seafood from New England and serving up great American classics; a 68-year-old Chicago institution that is producing some killer veal parmesan and short rib dinners; and a Philadelphia diner that is producing some out-of-this-world American dishes, all day long.
