The ever-evolving roster of shops at the Caesars Palace emporium gets a new addition this fall with fast-fashion retailer H&M taking over the 60,000 square-foot space formerly occupied by FAO Schwartz. This flagship location will be the largest H&M in the United States. (We just hope they keep the Trojan horse.) At the other end of the price spectrum, the diamond-deprived will find a healthy selection of gems and baubles at the new Cartier outpost, which will be double the size of the previous location. Both open fall 2010 at the Forum Shops.
