Andrew Zimmern shares a tour of the Iowa State Fair, one of the largest and best known state fairs in the U.S. A gastronomic trip through the 445-acre fairgrounds reveals fresh, locally grown sweet corn, baked sausage cavatelli and Dutch letter pastries. Vendors also serve up a dizzying array of sandwiches, like fried pork tenderloin, loose ground beef and the iconic Italian Gizmo.
