The correct name for this business is "US Airways Club & Business Center" as in the photo I added. In typical Yelp fashion, not only is the name incorrect, but the incorrect information is locked in so no updates can be made. Bravo! As a Yelp shareholder I strongly object to the idiocy.
There's a single terminal building at Charlotte International Airport with two US Airways Clubs. One is located on Concourse B between gates 3 and 5. The other, which includes a Business Center, is located on Concourse C at the intersection of Concourse D.
The one on Concourse C is quite large, quiet, and comfortable with complimentary wireless, snacks, soft drinks, and draft beer. It makes a nice excuse to arrive early for your flight.
