The Long Island Pizza Festival is set to return on Sept. 19 at the Nassau Coliseum Outdoor Plaza. “This is a festival to celebrate one of the richest parts of Long Island culture, which is our pizza community,” says Frank Antonetti, co-founder of the Long Island Pizza Festival. It’s a beautiful, beautiful venue and they’re giving us an amazing place to put it on. “Not only is it going to be a beautiful day for Long Island, but we’re also backing a beautiful cause,” he says. The Long Island Pizza Festival will take place on Saturday, Sept. 19.
