I luckily went here on a day when it wasn't too hot, but if ti had been, it would have been miserable. With that being said, they have a lot of nice stores to choose from. I am not big into name brands myself, but I do love me some Juicy Couture and they have a good selection. Sometimes I just make a beeline for the back of store where the super clearance is at and you can usually find stuff for even better prices. And no one has to know unless you have snooty friends who actually care what "season" your clothes are from.
Also, watch out for tourists from Asia: they are ferocious when it comes to buying purses and carry so many shopping bags that they take up half the walkway.
