Authenticity is central to Collette's cuisine itineraries in Italy. What this means is real Italian dishes will be served at these restaurants — something that might cause some culture shock for those expecting spaghetti and meatballs or pepperoni pizza.
As Collette says, "some foods (especially Italian-American) make Italians want to cry. They take their food very seriously and it hurts them to see what others have done with their great, great, great grandmother's recipes."
