With so many great BBQ options in Charlotte, you might try a chain like City Barbeque for convenience but the food and service are your standard fare, in my opinion.
We brought a large (10 people) group in for lunch and it took quite awhile for them to complete our order. I get the feeling they are still working out some kinks in their system.
The food was solid for the most part, portion sizes were decent for the price. I would probably go back if I'm in the area and have a taste for BBQ but not sure I'd go out of my way to return.
