What can I say? The biggest indoor LED screen in the world speaks for itself! There are lots (and by lots I mean probably hundreds) of plush loung-style chairs for viewing, lots of betting windows (prob around 15-20), plenty of bars and servers, and it's easily accessible from the main casino area.
Full disclosure: I only spent about 45 minutes here (the time it took to wait in line to place a bet on Super Bowl Sunday) and it was chaotic, to say the least. People everywhere and loud! It made me wonder if anyone was actually able to hear the commentating of the game.
There's a separate entrance for the superbook itself so if you're not already in the hotel/casino, you don't have to mess with valet parking or a long walk from self parking.
Away from the strip but still close enough to all that action, this is a sports book that I could see myself coming to again and again to watch an important event.
