I am driving back and forth from NC to Washington DC for the third time in a month and realized I haven't really tried any Virginian barbecue.

I am a Korean immigrant who's in love with American barbecue. In my senior year in college, I traveled around eastern NC to document barbecue places for a school project.

Given that my barbecue experience is mostly NC BBQ, I would like to try some Virginia style barbecue. However, I don't want travel too far away from the route, so I am looking for barbecue places near I-85 and I-95. Any recommendations?

I recently learned of the existence of this unique DC condiment and thought of it as good gift for my recent travel to DC.

I tried to find a place to purchase the sauce before I was leaving DC around Georgetown but most Chinese restaurants in the neighborhood didn't carry it (I guess the neighborhood's too fancy for that).

I ended up buying it from the nearest Chinese restaurant & bar in Arlington that was also a sushi place (always a bad sign).

To be honest, I didn't try the sauce and just left it in the fridge because I wasn't exactly thrilled of the place.

Well I have to visit DC next week again and wish to make another try. Any recommendation of good place to purchase the mambo/mumbo sauce in DC?

P.S. The receipt from the restaurant I purchased stated it as "general tso's sauce" instead of mambo sauce. Are they the same thing?
