He is the author of multiple food-based books. His first book, The Dictionary of American Food &Drink, was called "groundbreaking"[19] as it was the "first book to chronicle [American] cuisine".

He went on to write more books including Eating Out: Fearless Dining in Ethnic Restaurants[22], America Eats Out[23]which examined America's eateries such as Pizzerias and the advent of the Submarine Sandwich, and Mariani's Coast-to-Coast Dining Guide in which he "conscripted regional food critics to write chapters relative to their part of the country"[24]. Kirkus Reviews suggested it should become "a part of every businessman's or vacationer's travel pack".[25]
He co-authored annual editions of Passport to New York Restaurants and was editor of Italian Cuisine: Basic Cooking Techniques. How Italian Food Conquered the World was published in 2011.[26][27][28]
