It was interesting. It's basically a surplus store mashed up with an un-dead theme. They had some useful items there such as knives, utility tools, some ammunition, but it's mostly a novelty store. You'll find all kinds of Walking Dead memorabilia strung around the store. There are also a couple of interactive games inside. One being a shooting game, kind of the like the ones you find at Bass Pro Shops or at some carnivals, and they had an interactive zombie door thing-a-ma-jig.
It's something worth visiting if you have some free time, but I wouldn't make a second trip.
