I stopped in here the other day for the free wi-fi and study spot at the cafe. The cafe is located right by the entrance to the mall so it can get a little loud at times. There are a lot of tables but not that many plugs so scope out the place and find a prime piece of real estate. :) Overall, good study spot and the food court in the mall is convenient for when you want a bite to eat :D.
As far as a bookstore, I can't say much since I only went in to study and nab wi-fi. Sorry to you, Borders! :) Maybe next time?
