I consider us lucky to have a Nike Town because there are not many U.S. cities that have one. This was also the first one to get the Nike ID station for customizing shirts, shoes and other apparel that I cannot think of off the top of my head. The prices for customization are surprisingly not too expensive either. Also, I do know this location gets brand new Nike products in stock or limited edition stuff can be ordered here (limited edition/new Kobe shoes, etc.)
Although located in the far back of the Forum shops, it is well worth the walk to because it is a massive 2 story store with alot of of apparel as well as nicely decorated athletic memorabilia. During March Madness earlier this year, they had mannequins wearing college jerseys. To gear up for NFL they had a setup with all NFL teams' top selling jerseys lined up. The second floor escalator has a nice setup of framed jerseys and photos of the men's Team USA basketball. Up top I recall they have a large clothing line for Nike golf and soccer.
Although I probably would not buy anything here because I'm more of an online/outlet shopper, this is definitely a store that tourists should stop by and visit because it is a shrine to all that is Nike.
