Every time I come to Vegas, regardless where I am staying, I have to trek over to Caesar's just to go to the Forum Shops. I have loved this place since I was a teenager and though there are tons of high end places, there are more than enough regular old places to shop as well.
Restaurants have come and gone (I miss the Stage Deli) but have found PJ Harvey's now, and luckily can spend hours here without spending a lot of money (unless I want to).
I will definitely be back!
