The best pizzas, like the worst Elvis impersonators, are cheesy, saucy, and often live in cardboard boxes. Sink your teeth into a doughy classic with today's Groupon: for $8, you get $16 worth of American fare at Rock City Pizzeria in Boca Raton.

The chefs at Rock City Pizzeria marry house-made pizza dough and sauces with an arsenal of toppings and a vast selection of breakfast, lunch, and dinner options. Harnessing the power of fresh bread and produce from local sources, the eccentric rock-'n'-roll-themed eatery doles out pizzas, subs, burgers, wings, and breakfast fare. Design a veggie-laden outfit for a 16-inch pizza ($12) with more than 20 styles of toppings ($1.50 each on a medium pizza), or scarf down specialty pies such as a 16-inch buffalo chicken pizza ($15 for a medium). Build a maze to house a 6-ounce greek burger ($7.95), or sink teeth into a 6-inch chicken parmesan sub ($6.95). Hungry commuters can grab a quick breakfast at any time of the earth day, including bagels such as the hawaiian, toasted and topped with cream cheese and pineapple ($3).
