The restaurant is called Good Stuff Eatery and is located just a couple of blocks from our Congressional office. The President's address might be 1600 Pennsylvania Avenue, but his burger is located at 303 Pennsylvania.
The place was packed, but the service is quick and worth the brief wait.
Celebrity Chef, Spike Mendelsohn (Bravo's Top Chef Alumni) is the establishment's owner and Michelle Obama and staff came and ate at the location a few days prior to my visit.
If ever in DC, check it out.
