That depends on what you mean by "came from". Yes, that's where he was born/raised, but his first meaningful experience as a chef was in New Orleans. From a culinary POV, New Orleans is where he came from.
Regardless of origin, his restaurants maintain a high level of consistency and quality and I'd definitely recommend people try them if the chance arises. (My fave is Tchoup Chop in Orlando FWIW).
Also speaking of Tchoupitoulas Street in a roundabout way, there's a small restaurant called Dick And Jenny's that I've had great food at. Bacon and Filet Mignon gumbo was the gumbo du jour! Talk about over the top awesome!
