Pizza is ubiquitous in American culture, thanks solely to its ability to double as a fraction calculator. Indulge in a numerator with today's Groupon: for $15, you get $30 worth of Italian fare at Estero Pizza & Pasta.

Estero Pizza & Pasta’s kitchen crew slathers hand-tossed dough in fresh toppings to create an extensive menu of pizza creations, partnered with hearty pasta dishes. Feasters can ignite stomach engines with a basket of fried calamari ($7.99) or play pick-up sticks with a bundle of fresh-cut fries ($2.49) before divvying up slices in a 10-, 14-, or 18-inch dough disk ($8.99–$18.99). Preconceived pizza inventions range from tried-and-true favorites, such as five-cheese and margherita, to innovative crust canvases, including the bacon-cheeseburger concoction, bedecked in meat sauce, bacon, and mozzarella cheese. Fettuccini alfredo ($10.99) and baked ziti ($9.99) round out a catalogue of 17 pasta bowls, each optionally intertwined with bacon ($0.99 extra), sausage ($2.99 extra), or meatballs ($2.99 extra) catapulted directly from the kitchen. The roster of individual-size, handheld treats includes a classic italian sub ($6.99)—a boot-shaped trifecta of ham, salami, and pepperoni with provolone—and a barbecue burger ($6.99).
