At the annual New Orleans Jazz Festival, which kicks off this weekend, food doesn’t play second fiddle. In fact, the Fest could be double-billed as a full-fledged food festival. Regulars — locals and visitors alike — love to hop from stage to stage at the sprawling fairground, dancing to everything from gospel choirs to Billy Joel to Trombone Shorty. But Jazz Fest fans also give serious consideration to their food agendas, making sure to hit favorite stands year after year. We like to zone in on the vendors who serve unique dishes that are hard to come by outside of this two-weekend event.
