37x5 - Diners, Drive-Ins and Dives

On this trip, Guy Fieri is divin' into dishes from real deal to really creative. In Portland, Ore., a 70-year-old icon serving up authentic recipes straight from the chef's Chinese hometown, and a jammin' joint in Oklahoma City getting groovy with chicken and biscuits and a funky signature specialty. Plus, in Philadelphia, a legit sandwich shop putting their own twist on the Philly cheesesteak.
