Zander,
We went for our 35th anniversary a few years ago(2004), and I was satisfied. Food was good, but you go there for the view. We went while it was still light out, and as dinner went on, night came and the Vegas Valley lit up. Cool.
I also remember that it was the first time I broke the $200 barrier for dinner for two, but I felt it was well worth the price for a very special night. They seated us at a booth that faced the outside directly. At first I didn't want to be there because it was on the inner rim of the revolving platform farthest from the windows; but I later decided this was the best view since we saw directly out.
I recommend it, especially as a special night out.

If cost is important, I hear lunch is cheaper.
