One of the first things I noticed on the electronic regisration system when I walked in was the wide variety of games going. Besides the normal small Limit and No-Limit Hold'em games going, they had 10-20 and 40-80 LHE, 10-20 NLHE and 4-8 O8. Later on, they got 5-10 NLHE, 10-20 O8 and 2-10 Stud and possibly 25-50 NLHE. They had 15-30 Stud for a couple hours before I got there. I have only been playing for a couple years, but this is the first time I have seen a casino get low limit Stud and Omaha games going at the same time. I was very impressed.
The ambiance of the room was nice. They didn't put a lot of effort into decorating it like the Bellagio or Wynn, but it has its own advantages. In most rooms, the TV's would only have 2 or 3 different games on. At Caesar's, they had 7 or 8 different games on the 11 TV's they had, including a hockey game on a Canadien network. It seems that if a televised sporting event is taking place in North America, you can find it here. The problem is that the TV's aren't that big (50-60"?) and since the room is so big, if you are in the wrong seat, you're going to be too far away to see your score. One other point to note is that the room is completely enclosed: you cannot see the room from the casino. You have to walk down a short tunnel to get to the room. This may mean fewer fish, but this combined with the radios make this the quietest room of its size you'll find.
The games were pretty tough. I played mostly 10-20 LHE and 10-20 Omaha 8 and I lost money on each in an otherwise profitable trip for me (I killed the 20-40 Stud game at Bellagio). I would say an aveage of 3-4 people saw the flop in the HE game and they were pretty agressive. The games here weren't as good as the competition (Mirage for LHE and Wynn for O8).
They hired experienced dealers for the room: one dealer said he had been working the tournament circut before. The games were run efficiently with no misdeals over the 10 hours I was there. These are not new dealers.
One problem with the room is the cocktail service. Although it improved later on, you could expect to wait 30-60 minutes for your drink after you ordered it early on, and the waitresses didn't come around very often either. The other problem was that the waitresses were UGLY. In some places, the waitresses weren't pretty, but they at least had decent bodies. At Caesars, the majority of their waitresses were in the 200-275 lb range. Their drink selection was good and you could buy food and eat it at the table, although this isn't a high priority for me. Overall, I would call the cocktail service pathetic.
The floorpeople were very well organized. It was probably because it was opening day, but early on they had 8 or 9 floormen walking around serving 15 active tables. The floormen were also very helpful, acting as chip runners when necessary (although they had dedicated chip runners). One interesting thing about the system is that some of the floormen were in radio contact with the registration desk. When a seat opened up, the dealer didn't call it out. Instead, the floor was supposed to notice the seat as he walked by and radio it in. I was impressed to hear a seat called 2 seconds after the floor radioed it in, but it could take 5 minutes for the floor to notice the seat. The radios were also helpful for dealing with interest lists. I asked a floorman to take me off a list as I was playing and he did it. I noticed an hour later that the registration desk didn't take me off, but I still like this feature.
Didn't specifically ask, but I think I overheard that they comp $1/hour.
