Since the only other Vegas buffet I've been to was the Wynn, the bar was very high for me on this one. The reviews seem to indicate that Wicked Spoon has gone downhill in the past few years, so all I have to say about that is I wish I were here when it was "great" because it's certainly pretty darn good now.
They have a huge variety of offerings (which I would expect at a Vegas buffet), but more than that, everything was fresh and very well prepared (with maybe the exception of the sushi which was good but didn't seem super fresh).
There were several chef stations where you can have something cut or whipped up for you fresh which was a nice compliment to the variety already provided.
The busser/server for our table was quick, and kept the mimosas flowing even before I asked. I would definitely recommend the Wicked Spoon for anybody looking for a good buffet on the South end of the Strip.
