Brand new store. Just opened. It's Microsoft's answer to the Apple Store. However, I didn't notice anything resembling a "Genius Bar" (though the place was so crowded I could have missed it).
Basically just lots of Microsoft products for sale. You could get them all at Amazon easier, and probably cheaper. Without a service bar of some sort I don't really see the point. I was able to see a Surface Type Cover on my smartphone for 25% less than they had in this store (and, in fact, I ordered one...saved $30 compared to this store).
If they have a service bar then add one star. Otherwise, just go to Amazon and order what you want.
