As others mentioned, this is a great place to window shop, people watch, and just enjoy the sights. We spent a few hours here with 2 other couples. No one bought anything but we still had a good time.
The blue sky with white clouds ceiling is cool but other malls in Vegas have it too. My wife loves the architecture here better than the rest.
I wonder how the high end shops that only 1% of the population can afford to shop in stay in business here.
