Like money, pizza can be traded for anything and is often in short supply on college campuses that don't believe in geometry. Calculate the value of pizza-pie with today’s Groupon: for $10, you get $20 worth of pizza and drinks at Shield’s in Southfield.

Since 1937, Shield’s has kept Detroit's pie-craving community in full flavor with deep-dish squares and a supporting cast of Italian and American menu items. Shield’s experienced pie farmers cultivate doughy pastures for a wide selection of specialty pizza crops. The Gold Medal pits sweet red bell and italian banana peppers against pear tomatoes and romano cheese in a delicious rivalry over taste buds' affections ($17.49/large). Conquer the eatery’s namesake—the Shield’s Super—scrumptious amalgamation of mushroom, onions, green peppers, ham, and pepperoni kept safe from charring under a protective blanket of brick cheese and Shield’s pizza sauce ($18.49/large).

Pizza-timid guests can sample a commanding menu of handheld edibles such as the grilled chicken pita ($7.49) or myriad burgers and sandwiches. Mount an expedition to excavate the Sunken Treasure—sweet sedimentary layers of Stroh’s ice cream, Sanders hot fudge, and whipped cream, concealing a warm fudge brownie foundation ($4.29).

• I am a big fan of Shield's pizza - it is deep dish... thick and doughy and the toppings and sauce are fantastic. – Valerie G., Yelp, 1/27/10
• The place is actually pretty spacious and the menu is extensive with bar foods and pizza varieties. I last had a meat-lovers pizza and potato wedges, and they both were yummy. – Cherice J., Yelp, 6/27/08
