Guy Fieri revisits an old favorite he's been going to for years in San Francisco, but nowadays it's his buddy who's on the line serving up cod rillettes and chowder with a surprise ingredient. In St. Paul, the Godfather of pasta is still servin' scratchmade everything, including a twist on mac and cheese, and in Superior, Wis., a neighborhood hot spot has added some new appetizers with influence from up north.

This time, Guy Fieri is cruising the neighborhood to revisit local hangs he can't get enough of. First up, in San Francisco, an Italian joint keeps crankin' out favorites like chicken marsala and eggplant parmesan. Then, in Philadelphia, an old-school, family-run diner is still offering up scrapple, crepes and apple walnut French toast at any hour of the day. And in St. Paul, a total dive has added even more Chicago-style staples to their menu, including a hot dog topped with giardiniera.
