With its equal portions, regional variations, and a careful system of checks and balances governing its toppings, the pizza is a perfect symbol for its native land, America. Get your slice of the pie with today's Groupon: for $7, you get a large Papa John's pizza with one topping (up to a $17 value with tax). Enjoy the carryout-only creation from any one of six locations.

Papa John's has carefully curated a menu stocked with robust topping options to adorn blank pizza canvases. Unify bubbly discs under a blanketing of freshly cut roma tomatoes, or spice up bites with jalepeño peppers. The pizzeria imports its black olives from Spain's Herrara grove, where they peak in plumpness and accomplish astounding feats of international diplomacy before populating Papa John's pizzas. Meaty options such as grilled all-white-meat chicken, filler-free spicy italian sausage, and hickory-smoked bacon add layers of heartiness to slices, and reinforcing mozzarella with parmesan, romano, or a blend of asiago, provolone, and fontina improves the genetic robustness of cheese.

Papa John's has been popping out perfectly personalized pies round the clock for the past 25 years. The pizzeria stays open late, making it the ideal eatery for impromptu pajama jams and uncontrollable sleep feasting. Though Papa John's sometimes offers discounts on pizza, this Groupon still is the best deal.
