Southern Nights Soirée

Ready to get gussied up in your finest seersucker suits or linen sundresses? The St. Tammany Chamber of Commerce's biggest fundraiser of the year brings casino games, an open bar, samples from area fine-dining restaurants, and both live and silent auctions to Fleur De Lis Event Center in Mandeville. Proceeds from the event—an opportunity to network with business leaders from across St. Tammany parish—enable the chamber to offer members relevant programs and services at reasonable prices. 7 pm–10 pm. $150; $250 per couple. sttammanychamber.org.
