+1. I've had some decent meals at Gordon Biersch (warning: carrying the smell of those garlic fries onto the plane with you may be cruel to other passengers), Old Dominion Brewpub and Tidewater Landing, but Harry's is a considerable step up from those places.

Vino Volo is an excellent place to stop by if you're only thirsty--and willing to be a little spendy--but its location at the far end of the C concourse is going to be an issue much of the time.
