In general, people in New Orleans cultivate a relaxed, informal atmosphere in keeping with the climate and easy-going lifestyle. Most people still wear business suits, particularly in traditional sectors, such as banking and law, or else ‘business casual' (without jacket). In New Orleans, as across America, many companies have instituted a casual dress day, usually Friday, where employees can wear jeans or other casual attire to work. With the city's warm climate, this is an especially popular trend. After hours, only a few top restaurants and hotels require men to wear a jacket and tie but smart-casual is more often de rigueur.

Socialising with clients is as important as networking with industry professionals. Industry and career-specific professional organisations provide networking avenues and many companies host ‘business after hours' events to encourage meeting like-minded businesspeople.

Because of the city's superb cuisine, business in New Orleans is often done over a meal. And restaurants here do not rush their customers! Hosts generally do not invite clients home unless they know them well. Business associates tend to exchange business cards at an appropriate moment, usually towards the end of a meeting. Gifts are not necessary, although small items, such as pens with the company logo, are sometimes appropriate.

Business hours are typically Monday to Friday 0900-1700. Lunch is generally taken between 1200 and 1300, or 1230 and 1330. Where alcohol is concerned, it is best to err on the conservative side, until the host's preferences are known. Many Americans stick to soft drinks at lunchtime, especially in the hot, drowsy days of summer; in a southern city such as New Orleans, the non-alcoholic beverage of choice is iced tea. By and large, people are health conscious and smoking or heavy drinking may be frowned upon in a business environment.
