For pizza, Pizzaria Paradiso (sp?) in Du Pont circle; it's about 2 blocks from the metro station. It's also near Phililps Gallery which is America's first modern art museum. It opens til 9PM on Thursdays if you like art.

For Italian, Galileo (expensive) or I Matti (moderate). Both restaurants participate in DALC and Transmedia. BTW DALC runs dining programs for AA, DL, NW, and UA.

Try Full Kee in Chinatown for for HongKong style shrimp dumpling soup with or without noodle.

If you are more specific about your preference as cusine, price, location and etc, you will get better recommendations.
