Rocco's Ristorante & Pizzeria
Deep, deep, deep in the suburbs is one of the best pizza places around. Rocco's is your typical red-checker table cloth suburban pizzeria, serving pasta along with pizza dishes. The pasta isn't worth the trip, but the pizza is (such as Anthony's East Coaster). Go during the special on Sundays and Mondays -- pitchers of beer are half off and Large pizzas are around $12. Otherwise go to the website and use the coupon to save money that you can apply toward the gas you spent driving out there.
