This hotel is so huge, I've been there a million times and I still don't know my way around completely. The Caesars Forum Shops mall is pretty cool. There's plenty of places to eat and drink. And there's a theatre with huge headlining acts (I saw Jerry Seinfeld there, my aunt is seeing Cher there).
I've played poker quite a few times in the Caesars poker room, and it's definitely one of the best in town. The have two rooms... the main room for cash games and another for tournaments. It's pretty well run, and if you call in advance you can get on the list for some games.
I think my favorite thing in this hotel is right when you come out of the elevators from the parking garage -- make sure you go through the door on the right. Trust me, it's awesome.
