Not one of the most elegant in Vegas, but certainly one of the most comfortable. MGM poker room has tons of elbow room and space between the tables. The decor is modern and the atmosphere is relaxed.
I've played there several times and I haven't encountered too many donkeys or fishes, most players are solid and serious. It feels like a solid home game.
They are usually very professional and try hard to make the game go as smooth and enjoyable as possible.
They come around a couple of times every hour. And managment will usually call them at the player's request.
They are very efficient in getting everything to run right. The waiting list is always up to date and the are usually standing around spread out between the table so they are readily available to the players.
I think you get like a dollar and hour for food comps. Not as much as it should be, but I've noticed that not many casinos comp as they should for poker.
