New Haven, CT (Est. 1925)
The oldest New Haven pizza joint around (and one of the 33 best pizza shops in the country), Frank Pepe is considered "the big dog" in town, and with two very good reasons: the Original Tomato Pie and the White Clam. Order either and you'll get the same smile on your face people have gotten since eating there back when the world was in black & white.
Brooklyn, NY (Est. 1924)
Not to be confused with Totino's, that famed pizza roll company that's never been the pride and joy of Coney Island, Totonno's is open to this day despite two major fires and a hurricane. Its thin-crust pies have been around for nearly 100 years, and are considered some of the best in NYC.
Utica, NY (Est. 1914)
A Utica tradition and member of the Pizza Hall of Fame, O'Scugnizzo's is known for its "upside down" pizza, where the toppings (sausage, peppers, mushrooms, etc.) go on before the cheese and sauce. Even though it started in 1914, it's moved solidly into the 21st century, as you can order its pies to be shipped anywhere in the continental US via its website.
Robbinsville, NJ (Est. 1912)
There might be some debate about which pizza shop can lay claim to being around the longest, but for our money (and Colin from Taste of New Haven, who did the hard work to catalog these legendary pizza spots), Papa's is the oldest, continuously run pizza shop in the country. The Tomato Pie is its creation, and it's still churning them out like it's 1912. And its high-quality pies haven't gone anywhere since then: we named them one of the 33 best pizza shops in the country.
