I'm planning a road trip to N.O. from Chicago for the Jazz Fest this year. Based on a prior post, I was thinking about traveling I-90 thru Cajun County up to Lafayette on my way back to Chicago. It will likely be the last day of the Fest, Sunday. Are some, all, most of the food places recommended on this board likely to be open on a Sunday? If not, can you help me narrow down the list? Thanks!
