In this April 12, 2014, photo, Chefs Martin Arrojo, left, and Ezequiel De La Torre, second left, Brenda Arrojo, right, prepare salad for customers, as Brenda's son Franco, second right, looks at them while drinking water at their home in Buenos Aires, Argentina. The website www.cookapp.com was launched in March 2013 and recently moved its headquarters from Buenos Aires to New York City. It works like a matchmaker, arranging intimate gourmet dinners between strangers. Chefs list when and where they will prepare particular meals; diners book what interests them, pay upfront via the app, then just show up and enjoy. (AP Photo/Natacha Pisarenko)
