We went fairly late after arriving into Charlotte from our drive from Atlanta. You pull up into a spot and a runner comes out to take your order, then brings you your food and you pay for it. You can also go up to the walk-up counter yourself.
I ordered fried fish with fries and coleslaw. My brother got pulled pork with onion rings and coleslaw; it also came with two hushpuppies. You also get a bread roll. The food was okay, but I wasn't particularly impressed by any of it. Prices are inexpensive and portions are decent though.
