Looking for traditional southern new years day meal in DC...
GB's is probably your best bet for the whole pork, greens, black eyed peas traditional meal served on New Year's Day.
You could also try Southside 815 in Alexandria they do the most traditional low country southern as far as I am concerned.
I have never been to these places, but you could give them a call too they are in the right area of town to do real southern: Creme Cafe and Oohs and Aaahs.
Vidalia does new age southern, but maybe they do a twist on the classics?
I bet Gladys and Ron's Chicken and Waffles in Largo, MD will have something (East Capitol Boulevard). They even offer a 10% discount to VA residents (I guess for makin the drive).
Have not eaten there, but being a Southerner, the menu makes me drool at times.
Just ate at Georgia Brown's for the first time when we were in DC last week. Very good collards. Hoppin John was on the menu, but none of us had it. Fried chicken was very good. Crab cakes a bit too salty, very sorry to say. Overall, we enjoyed the place and would recommend it.
