This is the better outlet mall in Vegas as far as I can remember. It's an outdoors shopping mall with a multilevel parking garage. Last time I went to the one at the other end of the strip I was really unimpressed and haven't returned since, so it's been a few years.
While it IS ridiculously hot out during a majority of the year, there are small cooling stations scattered about. All of the bathrooms and stores are well air conditioned and there are vendors or machines dispensing drinks at frequent intervals. Still, I'd come around sunset due to personal preference as I'm a nocturnal lass and dislike excessive sun. No, I don't sparkle. ;}
I find this a fun place to come and window shop or people watch. It's also good exercise, doing laps around the large rectangle trying to find any cool stores I may have passed by first time around. There are a lot of fashionable foreign people, most likely drawn by the Armani Exchange and likewise stores dotted throughout. There are stores suited to a wide variety of budgets if you're willing to look around. Even the American Apparel store had some decent prices on things when I ambled through!
While I didn't eat in the food court this time, I remember it being uncomfortably hot and the food unpleasant. There's a sushi restaurant and a Starbucks, plus multiple vendors, so it shouldn't be too hard to find quasi-appetizing edibles. But really, who goes to the mall to eat? It's all about the shopping!
