Eating is necessary for human survival, along with breathing, sleeping, and remaining still while a curious velociraptor rummages through your closet. Practice survival tactics with today’s Groupon: for $20, you get $40 worth of Cajun fare at Ragin Cajun. This Groupon is valid at Ragin Cajun's three locations in Houston and one in Sugar Land.

The Mandolas, Ragin Cajun's founding family, fill menus with flavors and ingredients hoisted straight out of Louisiana. Bowls of jambalaya ($6.99) simmer smoked sausage, braised chicken, veggies, and fistfuls of creole spices in piquant tomato sauce, filling dining areas with a warming bouquet of aromas. The 8-inch catfish po boy ($8.49–$8.79) decorates a toasted french baguette like a chef's dorm room with bundles of tomatoes, shredded lettuce, and other fixings. A basket brimming with fried crawfish tails ($13.99+) plays a lively zydeco tune to an assemblage of time-tested southern sides such as hush puppies, dirty rice, and creamy coleslaw. The restaurant's gumbos ($5.99+ for a cup) cloak a plethora of meats in hearty roux and tender rice to grace diners with warm, fluffy victuals without the hassle of steaming a cloud.
