Every time I go to Vegas I try to play in poker tournaments that I haven't tried before. When I went back in December I played in 10 tournaments in six days, mostly smaller ones (Harrah's, Riviera, and Treasure Island) and a few larger ones (Caesar's Palace, The Venetian, and here). Having played in tournaments in over 50 Vegas Casinos I can say that this is the nicest poker room by far.
The chairs are fantastic, and the layout is second to none. The large playing cards hanging from the ceiling are simply pieces of art. The staff knows how to run a tournament flawlessly and the floor personnel manage the games seamlessly, without being intrusive.
The tournament buy-ins are not excessively large ($125 as mentioned in other reviews), but they are deep-stack and can run 8-10 hours. Try lasting that long in front of a slot machine or at a blackjack table for that much.
I finished just outside the money in my tournament here. The experience was so good I may not try any others the next time I go. If you are looking for an experience that is close to simulating the WPT/WSOP events without having three days and $1,500 to spend this is as close as you will get. First prize in my tournament was just over $5k. Not WSOP money, but still enought to make you feel like you accomplished a pretty good victory.
