Guy Fieri checks out some great family-run joints including a Baltimore favorite for pit beef with Ace of Cakes Duff Goldman. Next in Miami, visit a stop with recipes all the way from Puerto Rico and in Salt Lake City, a classic drive in burger joint.

Guy Fieri heads for three great diners that viewers e-mailed to recommend: In Baltimore, a gleaming, family-run place with a huge menu ranging from burgers, to goulash, to home made shrimp creole; in Salt Lake City, the diner that's heavy on tattoos and 1940s decor, where they're brining their own corned beef for hash, and smoking their own salmon; and in Minneapolis, the diner run by a CIA trained chef, whose specialties now include fried pickles and chicken and waffles.
