Grabbing a quick, tasty and affordable bite at Duomo can be challenging. Luckily, those in the know will always head to Luini to quickly silence those hunger pangs. The Luini family have been serving up the southern Italian speciality, panzerotto, to hungry milanesi since 1949. These delicious dough parcels are stuffed with a combination of mozzarella, spinach, tomato, ham or mushrooms and then fried or baked in a wood-fired oven. A standard tomato and mozzarella panzerotto costs about €3.
