I love 24 hours of food! Yes, you got that right, 24 hours. I luckily had the pleasure of being in close proximity to the location at the Quad without even knowing. So glad I was. I experienced the early morning crowd (I'm not sure how people get up for breakfast in Vegas, I just happened to be waiting for my hotel room to be ready) and the late night I should eat a lot of food before I make it back to my hotel room at 4am.
It's a ton of food, it's all good. Also, the alcoholic drinks are amazing at any time of day. It's fairly large,but wait times can be really long. I noticed in the morning it's good to get there before 9:30am, the rush comes about then. Late night, no worries, you'll be fine.
I could tell you what I ate, but it really doesn't matter, it was good. That's all you need to know. Go there pick something interesting and eat it. Your mouth will thank you.
