We stopped by Concord Mills while in the area just to have something to do. It's a bit out of the way for us and ended up not really being worth the trip.
The mall has a lot of the bigger name stores, and I liked seeing a Best Buy and Bed, Bath and Beyond attached to it. Some of my other personal favorites like Old Navy and GameStop were also there, and I thought it was cool to see a Lego store. The food court also seemed to offer an array of options, though we didn't stop to eat anything.
With the size of the mall comes the crowds, and this was the biggest turn-off. It was so mobbed inside that it felt like it was Black Friday and everyone was rushing to get their holiday shopping done. Then I almost got ran over by this train that actually runs through the mall's foot traffic...not exactly the brightest idea.
In the end, bigger malls attract bigger crowds, and it's just not worth it. I'd much rather head on to the Northlake Mall which is not only closer but doesn't give me a case of claustrophobia.
