A no-frills po boy shop between Royal and Chartres, Mr. Ed’s turns out the New Orleans lunch canon — dressed po boys, gumbo, jambalaya, and Southern sides — in generous portions. The blackened redfish po boy is the one to beat, and you can wash it down with a 32-ounce pitcher of margarita or Long Island. Part of the local Mr. Ed’s family of restaurants, it’s a dependable Quarter pit stop.
