Alcoholic beverage sale policies vary throughout NC. What is true in one county doesn't necessary carry over to the next, even within the same county there may be big policy differences. Some "wet," some "dry." Some mixed drinks, some off-site consumption only. Some areas prohibit all alcohol sales. North Carolina has 100 counties.
If you are interested in Huntersville, someone over in the Charlotte Metro Area Forum can probably help with the details for that area.
