I have to quibble with the DC picks as well.
Food at Galileo is good. Kinkead's is overrated. But Jeffrey's at the Watergate?
Personally, I'd head outside the city for one of the private rooms at 2941 in Falls Church. Outstanding food, possibly the best food in town right now, great views, and unobtrusive service.
But that's just me. But where does business actually get done? The steakhouses... The Caucus Room, The Palm . . .
