For this trip, it's Guy Fieri's treat! On Maui, musician Mick Fleetwood and his kitchen crew get the royal treatment when the Fieri family stops by to whip up lamb with mint pesto just for them. Then, when Guy first stumbled on a diner out in Delta, Wis., he just had to share it. Now he's back again, and the hash browns have a whole new look. Plus, the third generation may have taken over a Houston joint, but the burgers and specials are still the same.
