Hmm--not sure about what's right there, but a 15 minute walk away or a quick cab ride is Teaism on 8th Street, which has both meat and vegan items on their menu:

I have to say vegan options near Union Station and the Hill kinda suck. If they're flying, why find something near Union Station, which is a train station?
