The Buffet at Monte Carlo was pretty decent for brunch. The price was right as we got this free from the MyVegas game on the Facebook. I might have felt differently had I paid.
The food was decent, not spectacular, but not bad. My favorite thing was an amazing olive plate with a selection of olives and roasted garlic... SO delicious. I posted a photo! I also enjoyed dessert here... there was a tiny little chocolate ganache-y looking thing that was sort of like chocolate spoon cake and DELICIOUS. Those two items were highlights for me. I also, personally LIKE having a drink station because I can't count how many times I've been at a buffet wishing someone would bring me a drink. Plus you have some mixology options... I made a delish half hot chocolate half coffee drink. YUM.
I don't know that I'd come back here if I'm actually paying, but I won't say to stay away or anything. The only weird thing is that such a nice hotel has such a mediocre buffet.
