"Crabby Jack's in Jefferson, LA"
Guy, You need to go to Crabby Jacks, an excellent "dive" just outside New Orleans, not far from the Rivershack Tavern, a place you have visited already. It is located directly in front of a seafood wholesaler, so the shrimp, oysters, calamari and fish are excellent. My favorite is the slow roasted duck po-boy, with the cochon de lait po-boy a close second. The food is excellent because it is the small, casual place of Chef Jacques Leonardi, owner of Jacques-Imo's on Oak Street in New Orleans. Check out the website here: http://crabbyjacksnola.com. I guaranty that you will not be disappointed. Rudy
