I will be meeting an old college friend for dinner. It will be the 1st time we will be getting together in years, so I want to find a place with great food where we will be able to really talk. She'll be in DC for a conference (staying near Dupont) and I'll be coming in via Union Station, so I thought a place on the red line would make sense. Close to Union would be ideal, but all the places I checked out were so, so expensive. Any suggestions would be great!
