Primanti Bros., sometimes called Primanti's for short, is a chain of casual dining sandwich shops in the eastern United States. Since its Pittsburgh founding in 1933, Primanti's has become a cultural icon of the region. The chain is known for its signature sandwiches made of grilled meat, melted cheese, an oil and vinegar-based coleslaw, tomato slices, and French fries between two thick slices of Italian bread.
