I used to live in Washington and I thought it was a great place for a semi-foodie like myself. There are certainly some great "uber-expensive" restaurants there, but there are a lot that don't break the bank. Matchbox, Heritage India, Jaleo, Luigi's, Old Glory...

I loved the pizza at Armand's (Chicago-style) and 2 Amys (Neapolitan).

Northern Virginia dining could be hit-or-miss, but the Great American Restaurants chain was my absolute favorite. The food and the service at all of their restaurants is top-notch. Have you been to Coastal Flats/Sweetwater Tavern/etc.?
