In Cajun cooking, the holy trinity is a riff on mirepoix that refers to onion, celery, and bell peppers and is the base for iconic dishes from gumbo to jambalaya. If the city of New Orleans had a holy trinity, it would be food, music, and the Saints. To understand the city's culture, go for Friday lunch at Galatoire’s, grab a bench at Preservation Hall, and catch a game at the Superdome. There’s also a burgeoning gallery scene along Julia Street and a handful of worthwhile museums, including the Contemporary Arts Center and the National WWII Museum.
New Orleans is a city that likes to get its party on, and its festivals are nothing short of epic. The most famous are Mardi Gras and Jazz Fest, but also of note are alternative music festivals like Satchmo Summerfest and Crescent City Blues and BBQ, plus the (free) French Quarter Festival. Even if you don’t plan your trip around a special event, there’s almost always a parade or a party going on somewhere in the Big Easy.
