9. Faccia Luna Trattoria
Faccia Luna has been serving up rustic pizzas in Clarendon for 25 years.  The pies come in four sizes and include popular options such as the Rucola, topped with arugula and grape tomatoes, and the provolone-rich Trenton Pie. The dining room is often packed on Mondays, when you can order a two-topping 12-inch pizza with two salads and two glasses of wine for $25.
