Of the 7 Q-joints that I've been to in Charlotte, Mac's has been the best - BUT, I've NOT tried "Sauceman's" or "Spoon's" (they were closed) yet!
In order from best to worst in my opinion - Mac's Speed Shop, Smokys Burnt End BBQ, Jim N Nicks, Bar-B-Q King Drive In, The Clock, Bodrick's Barbq Rib Tips, and Yorkmont Cafe.
I believe that "Ranucci's BBQ & Grill" next door in Belmont beats all those joints in Charlotte!
