Whoever designed the cafe here is afraid of electronic devices and groups of 3 or more people hanging out. Is there a medical term for that phobia? 18 Tables in the cafe with only 1 PLUG! That is ridiculous. The tables have two chairs, but can only fit books/product for one person. If you have more than one friend and/or want to sample more than one book, probably not the best Barnes & Noble for you.
They do have a nice security guard that greeted me when I walked in. I am guessing he is there just in case the seven dwarfs want to come in and use the one plug for their toaster of the month meeting.
If you are looking for a Barnes & Noble with plenty of plugs and a bit nicer neighborhood, check out my review on the Summerlin location. That is my go-to B&N even though it is a longer drive from the strip.
