It doesn't get much better than the Bellagio in Vegas.  I go here every time I visit just to walk around inside.  It is beautiful and the glass artwork is worth the view alone.  They have their seasonal indoor garden which is stunning.  The fountain show in the front lake is a must-see for anyone new to Vegas.  I REALLY love this place.  \"O\" is here and it is one of the best shows on the strip.  I am pretty sure it is gone now but there was a priceless artwork collection there a while back that was worth the price of entry just to see some originals from famous artists.
