Starting Friday through Tuesday, Landry’s Seafood House, a 17-unit chain owned by Houston, Texas-based casual-dining operator Landry’s Inc., is running a Mardi Gras social media contest. To participate, patrons must follow the brand on Instagram, visit a location in Mardi Gras attire and post a selfie with their “krewe,” or group, and share the photo on Instagram with the hashtag #landryskrewe. The first-place prize is a two-night stay at The Golden Nugget in Las Vegas as well as airfare for two and ground transportation from the airport to the casino and back. The second-place and third-place prizes are a $100 and $50 Landry’s gift card, respectively.
