We're two serious chowhounds looking for quality NOLA nosh. We are in town for 3 days, 3 nights, 9 meals and looking for quality food. We love the hunt for the restaurant as much as the food itself, and so we shy away from well-publicized places...we are willing to make exceptions of course. We hear that Central Grocery's muffaletta is the best but we are stumped for places to go for the best oysters, po-boys, and white shrimp. Any advice would be helpful - we'd really like to avoid going to "Mother's"!!
