Thanks for the help, everybody! Think I'll check out J&G Steakhouse.... sounds great.
@hppyheather, it's a client lunch, so just a couple people. no women, just a couple gents who work nearby.
Thanks, again, for all the recs. Will have to try Againn next time I'm down there...
I'm planning to be in DC next week and could use any recommendations for a nice business lunch. Walking distance would be great.
