I am inherently suspicious of a place where people put peanuts in their Pepsi, and mustard in their barbeque sauce.
I never did get the peanuts thing, but there's a BBQ joint on almost every corner. One of my regular stops is Maurice's. http://www.piggiepark.com/
He got into a little dispute regarding flying the Confederate flag outside his restaurants several years ago and a lot of retailers stopped carrying his sauce. It had an interesting taste - had apple cider in it.
Bessinger's Barbeque is run by his brother. Same recipe, just a difference of opinion regarding the Southern Heritage Museum thing (or so the story goes).
