Pat's BBQ (Salt Lake City, Utah) • Blow Fly Inn (Gulfport, Miss.) • Tune-Up Cafe (Santa Fe, N.M.) Guy Fieri uncovers some places the regulars keep piling into: In Santa Fe, a little café serving El Salvadoran specialties; In Salt Lake City, a barbeque joint where folks line up for the house special -- burnt ends. And on the Mississippi coast, a joint on stilts where they re doing Creole favorites.
