521 is hands down the best BBQ in the Charlotte area. We've tried Spoons, Bubba's, Mac's, etc etc. They have the best. The pulled pork is smoked for 14 hours, ribs are great and they serve the best BBQ chicken you can find anywhere (only on Fridays.) Don't miss the hushpuppies...the best I've ever had.
If you stop for lunch, get there early. The line wraps around the building.
