This popular West Chester Cajun restaurant and bar prides itself on its authenticity—the seafood courtbouillon and alligator jambalya are just two of the Cajun specialties here. So of course, the place is going all out on Fat Tuesday with a live crawfish boil, half-price crawfish bisque, and all-you-can-eat jambalaya, plus $5 hurricanes and $2.50 Abita beers (a Louisiana favorite).
