The air quality (circulation?) was worse of all the places I went to. It was loud, smokey, and the tables with the rails made it seem fairly cramped for 10 players. Not comfortable.
Lots of aggressiveness by people who were pushing 2nd pair or those pretending to be weak. Players at my table were obnoxious and not that fun to play with.
Dealers were fine. Nothing out of the ordindary or above and beyond the call of duty.
Best part of the MGM Grand poker room were that the waitresses were very attractive. Drink service was fine and quick as well.
People at the desk seemed less than friendly when I posed questions regarding the games. Those at the cash cage were fine though.
$1 an hour. Those were the only ones I was aware of. Just swipe your MGM/Mirage players card, and you're ready to go.
