Some places already mentioned that deserve repeating. For those of you in the WAS area, Captial Q near the MCI center/Chinatown in DC is pretty good. Saltlick in Austin has some great brisket and flavorful sauces, too. In fact, it's worth routing through Austin just to get some of it from their airport store.
And now to start some fights...
The KC style BBQ brisket at Arthur Bryant's just wasn't up to the top-end Texas brisket I've had. It was a little on the dry side. The ribs, however, were great. North Carolina BBQ? Vinegar and pork? Thank you for playing, please try again.
