Pizza is traditionally circular, as its original octagonal shape caused patrons to simply stare at it and wait for the diner on their right to move. Pave your throat’s thoroughfare with cheese with today's Groupon: for $10, you get $20 worth of pizza, pasta, sandwiches, and drinks for dine-in only at Felix & Oscars Chicago Style Deep Pan Pizza, valid at the restaurant's locations in Des Moines and West Des Moines.

Felix and Oscars' menu bursts with pizzas plastered with more than 15 toppings and pasta dishes ladled with house-made meat sauce. Cooks roll cutters through 17 specialty pizzas ($17.95+ for a large) baked atop three styles of crust, including authentic Chicago-style deep pan, traditional thin crust, and the signature cheese-topper style, which blankets deep-pan pies with mozzarella, cheddar, and romano cheeses. Several pies can claim gluten-free status, as can such specialty pastas as the Penne Tomas, a cavalcade of italian sausage, roasted peppers, and portobello mushrooms ($12.95). The chicken-parmesan sandwich wraps marinara, mozzarella, and seasoned chicken breast in a bready cocoon so that diners can carry it with them while they explore underneath the table ($8.75). Since Chicago-style pizzas bake for about half an hour, customers may opt to call ahead to expedite orders.
