Book excerpt: The votes are in! The Bertolizzi siblings are headed to Philadelphia for their latest great culinary adventure. When Zia Donatella comes to live with the Bertolizzi family, little do Alfie and his older sister, Emilia, know what's in store for them. Zia Donatella is determined to show them how a home-cooked meal is better than even the best takeout pizza. And when Zia's plan actually transports Alfie and Emilia to famous food cities around the world, they learn firsthand how food can not only take you places but also bring you back home. In this adventure, Zia sends the entire Bertolizzi family to the city of brotherly love - Philadelphia! Known as the "birthplace of America," Philadelphia welcomes the family with its historic blend of colonial buildings, national landmarks, and equally revolutionary cuisine. Their Philadelphia tour guide, Emma, shows the family that foodie destinations like Reading Terminal Market and 9th Street have as rich a history as the Liberty Bell.
