Four thousand people all dressed in white met in Lower Manhattan's Rockefeller Park for what's being called the world's largest dinner party.
The event is called Diner en Blanc.
Guests bring their own picnic, china and silverware, as well as white tablecloths, tables, and chairs.
Celebrity chef Todd English also prepared a special dinner for guests who ordered in advance.
More than 100,000 people participate in the event in 50 cities worldwide.
It began 26 years ago in Paris.
This is the fourth year it's been held in New York.
