This is a great store. They have well-trained employees who will help you find whatever book you need.
They sometimes could do with more chairs, since Duke and UNC students like to hang out on the weekends and study. So I try to get there during the week in the morning.
Nothing really different from the other Barnes and Nobles I have been too, although they seem to have a greater selection on the clearance items (possibly because students take up so much space on the weekends and do not leave much space for book buyers to browse).
