The 25-year-old actress, donning a black Marios Schwab dress paired with Fallon Jewelry and Burberry beaded heels, attended the celebration, which featured three of New York’s top culinary talents serving up their own culinary delights for guests to enjoy.

Fashion designer Charlotte Ronson, co-founder of Foodspotting Soraya Darabi, and film director Max Winkler hosted the event, and DJ Harley Viera-Newton and DJ Ana Calderon provided music for the evening.
