This NEX is divided into two buildings. The building closest to the road has a uniform shop, sports clothing, shoes, and the food court. It also has gift, shipping, and personalization products (name tags, plaques, etc). The building further to the east, closer to the gym, has food, electronics, a barbershop, a GNC, and other items.
Although this isn't the largest exchange, I think it is a great one. It was built inside an old hangar and has a very cool feel. The selection and location are both very good. I recommend the NAS Pensacola Exchange - Aviation Plaza.
