For airport BBQ, it's pretty ok.
I was stranded in Charlotte and grabbed dinner here. Plates (meat, 2 sides) run around $13-15 which really isn't terrible for BBQ, especially in an airport.
I opted for smoked turkey which was pretty good but probably pumped with brine since it was moist but really salty. For sides, their mashed potatoes were great - really well seasoned, and they're definitely real & not instant. The Mac and cheese on the other hand is an abomination - flavorless mush which went uneaten after a bite.
Dinners come with cornbread or hush puppies. I opted for cornbread (because I don't know what hushpuppies are) and it was moist, fresh and still warm. Meats are served unsauced and there is only one rather sweet BBQ sauce option which I passed on.
The people working the line were nice, there are lots of side options, the portions are good and the prices are decent. If you're stuck in CLT and the Chick-fil-A line is 50 people long, this place is a good choice.
