A great row of galleries here by Aria and the Crystal shopping mall. They have a sizeable collection of Chihuly pieces. Not nearly as good as the Chihuly Museum in Seattle but if you can't get to Seattle this is great place to visit.
There was also a photography gallery that does not allow pictures to be taken and a sculpture gallery with works of Richard Mac Donald who specializes on the theme of Cirque du Soleil. A good place to look at some beautiful art pieces for free.
