Hello VEGAS !
I adore this mall and usually make a whole day of it when I'm visiting! The Forum Shops' atmosphere and frenetic energy of people, designer stores, light shows, and endless food choices can be overwhelming at first.
Anyways, I've bought clothes here at various stores and everyone is almost always nice and inviting. Just be warned that this not your everyday JCPenny, Sears kind of mall so make sure you bring lots of cash, an AMEX card, or your parents. LOL !
