For anyone who has tasted good eastern NC vinegar-based BBQ pulled pork, it's a hard thing to forget. I'm a NC boy myself, and have been in Cali for almost ten years. I finally found (after a lot of searching) a truly authentic pulled-pork sandwich.
The name of the place is Kill Devil's (after Kill Devil Hills, NC, where the original sits) and serves a _perfect_ rendition of what I remember from back home. It's located on El Toro Road (Orange County, take the 5 south to El Toro Rd, turn left) about a block from the freway. The pulled-pork sandwich will cost you about 5 bucks.
