Greg Cox, the food critic in the Raleigh News and Observer, publishes a blog called the Epicurean. He recently posted Where to get your barbecue fix about Triangle barbecue restaurants.
Greg recommends four restaurants: Allen and Sons (north), Rub's (Morrisville), The Barbecue Joint (Chapel Hill) and the Q Shack (Raleigh).
The two barbecue restaurants in Chapel Hill are superb. Rub's is alright. We agree on three out of four.
My experience with the Q Shack has only been in Durham. I will need to check out the Raleigh location. I would have exchanged the Q Shack with one of the Danny's restaurants (RTP, Cary, Morrisville).
I will continue to track Greg's blog and post here his comments on barbecue restaurants.
