Guy Fieri searches out some classic joints doing America's favorites: In Baltimore, the place where they've been making Coney dogs the same way for more than 80 years; in Austin, the late night hangout where they're fresh-roasting Serrano peppers for one of their burgers, and serving Texas-hot buffalo sauce on another; and the Minneapolis dog and burger dive where one of the specialties is something called a Hairy Brain.

Guy Fieri rolls out for ice cream, Triple D style: With visits to a Norfolk, Va. drive-in for an original waffle cone, an Arizona creamery making Italian gelato in all flavors and a New Orleans favorite doing huge sundaes with 400 flavors.
