Spent a nicer weekend with the family in DC. Sunday night before I took the train up to Philly, we went to a hole in the wall BBQ joint called: The Federalist Pig - https://www.federalistpig.com/
Fun place, excellent BBQ, incredible side dishes and great desserts. Yelp said that they can run out of items and we got there early (about 5:30 on a Sunday night). Our timing was good in that they had the complete menu available, hwoever they proceeded to run out of items while we were eating, making up happy we didn't show up at 6 like originally planned.
If you find yourself in DC, stop by.
