The New York Pizza Project has spent years documenting a tasty and essential part of life in New York City.

Call it a slice of life.

Pizza is a guaranteed conversation starter and now there’s a book about the people and the places that provide the tasty meal.

Gabe Zimmer and his friends grew up in New York City and they spent the past 5 years compiling the pictures and stories. They self-published the book after a successful Kickstarter campaign. It’s available on their website and at select NYC locations.

They focus on the people behind the pizza. Although, they do have their favorite slices. You can add your ideas on their site.
