We have visited NCC numerous times in the last couple of years. Unfortunately, they are often times hit and miss. While the St. Louis ribs are about the best around, the chicken is usually dry and some sides are overcooked. Location is not their best friend either, hidden away in a small shopping center, and if you don't have the exact address you'll easily miss it.
If you catch them on a good day, though, you'll probably enjoy it. Sign up on their website for emails and get the daily deals.
