A LOT OF PEOPLE think that we just do events, and I’m cool with that, because I like the element of surprise,” says Jon Gray. “But we’re ready to spread our wings.” Gray, 32, is talking about the future of Ghetto Gastro, a six-year-old culinary collective he co-founded in New York and runs with a trio of chefs: Malcolm Livingston II, 32, Pierre Serrao, 30, and Lester Walker, 37. Livingston, Serrao and Walker have worked in kitchens with chefs like René Redzepi, Carlo Cracco and José Andrés, among others, but it’s Gray, who studied marketing at New York’s Fashion Institute of Technology, who functions as the group’s CEO.
