For nearly a century Columbus, Ohio pizza parlors have served up delicious meals by the tray and by the slice. This history goes back to the 1930s, when TAT Ristorante began serving pizza. Today, it is the oldest family-owned restaurant in the city. Over the years, a specific style evolved guided by the experiences and culinary interpretations of local pizza pioneers like Jimmy Massey, Romeo Sirij, Tommy Iacono, Joe Gatto, Cosmo Leonardo, Pat Orecchio, Reuben Cohen, Guido Casa and Richie DiPaolo. The years of experimentation and refinement culminated in Columbus being crowned the pizza capital of the USA in the 1990s. Author and founder of the city’s first pizza tour Jim Ellison chronicles one of the city’s favorite foods.
