Stomachs only growl when they're hungry or preparing to bite the hand that keeps tickling them. Tame the beast within with today’s Groupon: for $10, you get $20 worth of Southern fare at River Shack Restaurant.

River Shack Restaurant's owner, Beau Phillips, sates appetites with a menu of sandwiches, burgers, and entrees fresh from the sea. Grilled and fried po boys ($8.95–$12.95) hold fillings such as rib eye, chicken, oysters, or catfish, and juicy griddle burgers ($6.95+) arrive au naturel or accessorized with toppings that include mushrooms, chili, or a jalapeño-studded fedora. Both the flounder plate ($13.95–$14.95) and the 16-ounce sirloin steak ($18.95) come flanked by a choice of two sides, such as house-breaded fried okra, baked beans, greens, and corn-bread muffin. This large wooden shanty of a restaurant abuts a fishing pier and the river's flowing currents, while on the inside, fishing nets hover above diners, hoping to catch the mermen who sneak in through the large open windows.
