My wife and are going to be in Washington in early May, staying near Dupont Circle for a week. No car (never owned one)so we're dependent on feet or public transportation. We're gonna need six dinners, costing from midprice (whatever that may be) on down. BBQ, Chinese, French -- anything goes. Russian would be nice; I ate in a Russian place some years ago, but it's long gone. So can you make some suggestions for a hungry hound? Thanx.
