I spent one afternoon in New Orleans at the Audubon Zoo. Food happened while I was there. The first thing I ate came from this nifty looking food cart called Roman Chewing Candy. Apparently this cart is a New Orleans landmark because I later started noticing it on postcards sold in gift shops elsewhere in the city.
The Roman candy didn't quite hold me over until I was done exploring the zoo so I stopped into a restaurant there called Cypress Knee Cafe. While all the other restaurants I passed in the zoo served typical zoo/theme park snack bar foods, Cypress Knee Cafe had a bit more interesting menu. They were located in the Louisiana Swamp section of the park, and had appropriately themed local cuisine.
