The best pizza restaurant in the world is in New York City, the organization 50 Top Pizza announced.

Una Pizza Napoletana, located in New York City's Lower East Side, regained the top spot this year after sliding to second place in the 2023 rankings. 

50 Top Pizza unveiled its list of the top pizza spots in the world earlier this week. It also released a top 50 ranking for the United States, Europe and other regions of the world.

Una Pizza Napoletana, or Una, is the only U.S.-based pizza restaurant in the top five of the world rankings. The only other American restaurant in the top 10 was Tony's Pizza Napoletana in San Francisco. 

Chef and owner Anthony Mangieri's pizzas are "an interpretation of the Neopolitan style," according to Una's website, "with a thin, chewy crust with puffy and perfectly charred edges as well as carefully selected, minimal toppings." 

Getting a pizza at Una is no easy feat. 

Open just three days a week, Una serves pizzas each night until it runs out of dough, according to its website. 

Its menu has just five pie varieties, plus a rotating "special pizza."

Each week, only about 400 total pies are made at Una. 

Each person is allowed to order one pie per reservation, the restaurant's website said. Reservations open two weeks in advance and extremely limited walk-ups are available. 

The reviewers at 50 Top Pizza praised Una for its excellent execution of relatively simplistic pizza concepts. 

"In a country always accustomed to putting everything on pizza, Anthony proposes only the purest tradition in toppings, with extraordinary quality ingredients. Marinara, Margherita, Cosacca and a pizza that changes every day, based on market ingredients," 50 Top Pizza said.

"The dough nods to the contemporary, but is so personal that it probably cannot be classified, good, tasty, true, it has the aroma and flavor of pizza," 50 Top Pizza said.

It advised any wannabe diners to "book in advance, as the wait times are quite long."
