In Gerald Addison’s mind, the perfect slice of pizza does not exist. The Michelin-starred chef, who mastered open-flame grilling at Maydan and Caribbean-style cooking at Bammy’s, turns his attention to pizza with the opening of Grazie Nonna within downtown’s sleek new Midtown Center complex (1100 15th Street NW). Starting Friday, September 23, dinner will be served daily (5 p.m. to 11 p.m.) with lunch coming soon.

After tasting a wide array of regional pizzas up and down the East Coast — from New Haven to the Bronx and Brooklyn, as well as South Jersey and Philadelphia — Addison struggled to land on an all-time favorite. “I visited so many places that simply blew my mind,” says Addison, who came to the realization that “the perfect slice of pizza may not exist, but that every day you can work to achieve greater pizza excellence.”
