Don't come here if you don't have lots of time.... or lots of money!!! I think this mall is fantastic- even though some stores are slightly out of my price range. They have a wide variety of stores though. Essentially, they have something for everyone. So if you are more Banana Republic and your friend is more Gucci, then it's a perfect place for all!
There's also a bunch of good restaurants. And don't forget the other section with the spiral escalators. It's the best place to walk out of the Forum Shops. In case you haven't noticed, it's a little difficult to find an exit. It's a well designed maze of shops to keep you wandering for hours if you don't know where you're going. You almost need a map to find the exit.
