Meh.
As far as Old Navys go, this one has only the basics. The more trendy and interesting items seem to bypass this location. If you need jeans or a basic t-shirt, then stop by. If you want some of the cooler items they've come out with in recent years, you'll have to go to the Arizona Mills location or the one in Mesa by the 101 and Country Club.
Also, sales selection is often pick over...you should just go to the Mills, honestly
