Located at the Las Vegas Premium Outlets - South.  It's a bit small, but it has a decent selection of toys and the prices were GREAT.  We were able to find Octonaut figurines (if you don't have kids who watch Disney Jr., don't bother asking what this is) that we weren't able to get at home and which were much more expensive online.  Win - win!  Plus the employees were friendly and attentive.
