The first requirement for a barbeque joint is that they have some sort of wood stacked up outside and a real pit running. By definition, barbeque can't be made ovens.
In general, barbeque is not made in big cities. The lifestyle is just too fast to do it right. Most of these places are tourist traps. If it's been on the Food Network, it's too commercial.
The best barbeque on the planet is to be found at Pete Jones Skylight Inn in Ayden, NC. It's about 2.5 hours from RDU, and is worth the trip from anywhere in the world. Words cannot describe how good this place is. It's the only Q joint I've ever eaten in and concluded that I couldn't make better Q at home.
As they say in NC, you can criticize a man's wife and his dog, but if you criticize his barbeque get ready for a fight.
