They may not be authentic-of-Italy Italian food, but giant plates of chicken Parmesan and bowls of spaghetti doused with marinara are some of the country's most-popular dishes. These Italian-American spots — often referred to as "red sauce" joints — serve heaping portions, often topped with their own red sauce made from a recipe passed down through generations. Dim lights, white tablecloths and some serious history complement the indulgent dishes you'll find at these top spots across the country.
