True, Sonny's is a chain and that hurts its standing as a BBQ joint. Still though, the food is pretty good.
It's pretty easy to call in takeout or order once you're there. There is a separate takeout area you go to in the restaurant. My friend and I only had to wait a few minutes for our food. I ordered BBQ chicken and she got pulled pork. Both meals - complete with two sides and cornbread - were so large that they fed us for days.
Here's a tip: The best Carolina BBQ can be found at church luncheons. Charlotte churches often have small festivals where you can get a plate of pulled pork, beans, slaw, etc., for $8 or $10. Try to save room if you can. They'll also be selling sweet potato pie and other Southern desserts.
