This buffet is great! We checked it out on our first night staying at the mgm despite the not so good reviews, and I am glad we did because the food was delicious.
80$ for two people and a TON of variety is something that I just can't complain about. I do prefer only eating food that I can pronounce, though, so this suited us just fine.
There are many other options on the strip with more food choices, that's for sure. But if you are walking around, most likely buzzed, and just want some good effin' food, I recommend going here.
