Authenticity is a virtue many of us prize in our restaurants. But Los Angeles is also a city where the California roll was born and the best pizza hews to a standard more Californian than Neapolitan. A panel of Los Angeles’ best-known chefs -- including Nancy Silverton of Mozza; Roy Choi of KoGi, Jimmy Shaw of Loteria Grill and Sarintip "Jazz" Singsanong of Jitlada -- visited Zócalo to discuss with moderator and Pulitzer-Prize-winning food critic Jonathan Gold what it means for food to be authentic, and whether the pursuit of authenticity is worth it.
