i m 14 and I ve lived in Nola all my life. If you go in the french quarter it is used there A LOT also in the 9th and 7th ward. Uptown around St. Charles you can here some speak french and also in mid city around Bayou St. john.
I am afraid Jessica is not correct, unless she is referring to people occasionally using words that are French.New Orleans is an American city and almost everyone speaks English as their only language. There are no neighborhoods where French is spoken. There are not even neighborhoods where Spanish is spoken widely, though many Hispanic Katrina workers remain in the city. New Orleans East does have a Vietnamese neighborhood.
