I'm admittedly new to FT, so please pardon if my few recommendations have already been discussed...

Upscale, offbeat American - The Carlyle (formerly Carlyle Grand) in Arlington (shirlington section). 703/931-0777. I like this one so much I have the # programmed into my cell phone.

Steak - Ray's the Steaks, Wilson Blvd., North Arlington. About the best value you'll find in the DC area.

Upscale - Colvin Run Tavern, Rte. 7, Tysons (McLean). Owned by same guy who owns Kinkead's in DC. Great food, service. Place is is surrounded by Tiffany, Hermes, etc. 'Nuff said?
