Unlike serpents, humans can't subsist solely on their own tails. Consume endless nourishment with today's Groupon: for $11, you get an all-you-can-eat buffet meal for two (up to $10.99 each) at Ponderosa Steakhouse & Buffet (up to a $21.98 total value).

Ponderosa Steakhouse & Buffet is a 25-year-old design with family-friendly incarnations nationwide. The Lansing locale dares patrons to scale a heaping all-you-can-eat buffet, where verdant mountains of crisp lettuce and fresh toppings inspire salads, and zesty chicken wings offer to awaken taste buds that fell asleep while eating cedar mulch. Second, third, and ninth trips yield juicy baked chicken with vegetables, multiple styles of cooked potato, and the gooey seduction of bubbling pizza by the slice. Weekends unleash steaming meats from red-hot grills and invite diners to sample unlimited fistfuls of sirloin steak, shrimp, and barbecue ribs.

Though Ponderosa Steakhouse & Buffet sometimes features a discounted price online, this Groupon still offers the best deal available.
