Went to Pure on a Thursday night and only the outdoor patio portion was open.  We got a table with an amazing view overlooking the Strip.  The crowd was pretty chill.  If you're looking for that \"Vegas\" club experience on a Thursday night, don't go to Pure.  However, if you're looking for a chill clubbing night, Pure works.  Regardless of the chill environment, my friends and I still had a great time.
