I had two great dinners at two very good restaurant during my recent business trip to Washington DC:

• San Vito Restorante Italiano in Springfield (locations also in Herndon, Ashburn, and Chantilly)
• Montana Grill in Crystal City (with locations all over the East)

I had the four cheese ravioli at San Vitos which was very cheesy and had a great sauce.  And I had the bison meatloaf at the Montana Grill which was very flavorful.

I highly recommend both places.
