Chicago protects the indigenous but endangered deep-dish pizza by shipping hundreds of slices into the countryside every year to roam on crusts not covered by cement. Indulge in a delicious legacy with today's Groupon: for $10, you get $20 worth of casual Italian cuisine at Chicago Street Pizza in McKinney.

Focusing on Italian eats of the handheld kind, Chicago Street Pizza's menu serves up a homemade spread of pizza, subs, and more. Cross the meal starting line with toasted ravioli ($4.95) or garlic cheezy breadsticks ($4.99), perfect for plunging into openly salivating mouth pools.

Those looking for heartier portions can use arm endings to hoist up a Chicago-style pan pizza (starting at $11.50), traditional thin-crust pizza (starting at $6.50), or stuffed pizza (starting at $11.50), which can all be crowned with an assortment of veggies and carnivorous candies (starting at $1.25).

Like a binder for holding otherwise unorganized toppings and savory geometry notes, French bread is stuffed to create an array of subs, such as the cold American sub, filled with ham, cheese, lettuce, tomato, onion, and mayo ($5.95). Traditional Italian pastas include the baked lasagna ($6.95), which stacks savories skyward to be toppled by bulldozing forks.
