We stayed at Treasure Island for two nights and I was pleasantly surprised.  For one of the older casinos it was very comfortable.  Check in was a breeze and we were early. Our room on the 27th floor, faced the strip and was quiet, comfortable and clean. The casino has lots of the latest slots and even though I didn't win a lot I did try some of the other casinos and they weren't giving away money either.  We had lunch at the buffet which was plenty adequate and service was good.  We had dinner at the Kahuna, the chicken sliders were awful but the waiter was great, we also had dinner at the coffee shop where the food was good but the service was awful.  If you're looking for gourmet dining this is not the place to go but for a low key fun time I would go back.
