You're on vacation, so take advantage of what they prepare best here. New Orleans has good food for people on any type of budget.
Traditional Cajun cuisine can be found in many of the restaurants in New Orleans. The Acme Oyster House, known for its raw and chargrilled Louisiana oysters, also offers gumbo, jambalaya, and red beans and rice. The restaurant was established in 1910, and has been at its present location, 744 Iberville Street in the French Quarter, since 1924.
The seafood: is fresh and relatively cheap compared to many places. Some think it is often best fried, but you can try seafood of a wide variety cooked many different ways here.
Oysters: are a popular specialty, gulped down raw, battered and fried, in a po' boy sandwich, or elegant Rockefeller style.
Crawfish: (don't say "cray" fish) is a popular dish here, usually boiled in a huge pot of very spicy water and served in a pile with corn and potatoes. If cracking open the shells and sucking the heads isn't your thing, try them with pasta or in sushi or any other way they're prepared.
Gumbo: is a tasty Louisiana traditional stew, originating in West-Africa and comes in numerous varieties. The vegetable base is traditionally okra (in West-Africa, the Wollof language word "gombo" means okra) with filé (sassafras leaves) used as a thickener. Seafood is the most common meat; but one will just as often find chicken, duck, smoked sausage or "andouille" sausage, the ages-old "gombo d'zherbes" (vegetarian) and other types of gumbo on many a menu. Gumbo is universally served with rice.
