Sounds like a business opportunity for you, good luck

Honestly that sounds kind of brutal. Google maps says it'll be like 4 hours from Dulles to Martinsburg via rail (you can do it, but it's a lot). I think VRE goes between Dulles and Union Station? You can take the metro (kind of a hybrid subway/commuter rail system), but requires transfers and would take awhile. The metro system is called WMATA

If you need to take train to WV, it's easier to fly to DCA/Reagan. Dulles is far outside the city, DCA is a fairly quick cab ride to Union Station

From Dulles, it's an ~hour drive to Martinsburg, per Google maps. So might better to rent a car or get a cab. That would cost more but save you hours. Or perhaps your kid could drive to pick you up, don't know is that's an option

Good luck!!!

Phrasing

I mean, sorry, hope you recover it.

Years ago I went to a friend's birthday dinner at Laylina in Falls Church.

That would have been when Dubya was still President so between that and my not knowing what would be authentic take the above with a grain of salt. but I recall a delicious meal and comfortable atmosphere. Fwiw, I've always had good meals at Lebanese Taverna, eaten at multiple restos plus the more fast casual cafe locations
