I may be changing trains in DC with a three- to four- hour stopover, probably late lunchtime, maybe very early dinner. I was hoping to get out and eat in DC but I've heard you can no longer plunk your luggage at the station for security reasons. If I have trouble checking my luggage early for the next leg of the trip and instead have it with me, I'll need to eat right at Union Station. I would love some suggestions on where to eat there. I want a reasonably relaxing meal but not really huge or rich, since I'll be re-boarding the train! Also, it's possible I'll be traveling on Saturday or Sunday (though more likely a weekday).
