Don't know if its been mentioned ITT but Vegas Mate [http://www.vegasmate.com/] is a really useful app for iPhone and iPad, it includes restaurant and hotel info & reviews, maps and general tourist info. It's updated monthly and it downloads data and stores it locally, meaning you don't need an internet connection whilst you're there (just make sure you update it before you go).
Good app, possibly was mentioned many moons ago.
Just been told that Binions has reopened the upstairs cardroom where they used to hold the WSOP, supposedly they've done a decent job on the refurb and it's good 'for Binions'
