3) Spontini: If you are longing for a fat, thick slice of pizza then Spontini is the answer for you. They have multiple spots around the city. The most popular one is in Duomo again it's better to have a take away because there are no seats basically you enjoy your pizza on foot indoors. You can have a half or whole pizza as take away. If you want the restaurant atmosphere then try Spontini in Corso Buenos Aires or Piazza Cinque Giornata.
4) Princi Bakery: This place is famous basically for everything. What they do labels as focaccia but trust me on this one you won't be sorry. The amazing taste will blow your mind. You can check the one in Corso Como or Via Italia.
