Pizza was serendipitously invented when a meteor crashed into an Italian kitchen, flattening a nearby stock of ingredients into a round pie and frightening a cat into delivering the new food to neighbors. Celebrate the interstellar origins of pizza with today's Groupon: for $10, you get $20 worth of pizza and grilled eats at Mama's Pizza and Grill, located in Sinking Spring.

The dough wizards at Mama's Pizza and Grill whip up an extensive menu of casual chow, including homemade pizza pies, cheesesteaks, chicken wings, strombolis, and calzones, in an inviting, sports-themed setting. Famished patrons can silence their growling guts with a supreme pizza loaded with pepperoni, sausage, green bell peppers, onions, and mushrooms, a barbecue chicken pizza, and a bacon cheddar cheeseburger pizza topped with ground beef, bacon, cheddar, and mozzarella, or customers can simply use the edible circles to finish a game of frisbee golf (each $13.99–$17.99 for flat; $18.99–$21.99 for stuffed). Meat enthusiasts will relish the 12-inch cheesesteak ($6.25) while wing connoisseurs will clamor for industrial-strength wetnaps after noshing on a plate of 20 buffalo wings ($9.99).
