Franco Pepe has been in business since 2012, but it was the Chef's Table: Pizza episode that helped catapult him into stratospheric popularity among pizza aficionados. He has built a temple to the art of pizza - Pepe in Grani - where all dough is mixed by hand, and toppings are curated from around the country, oftentimes transformed into unrecognizable shapes. We got a rare tour of his space, in a renovated 14th Century structure hidden away on a tiny side alley.
