My daughter is a teacher and keeps in touch with her former students. 2 of her former students are in Vegas right now.
Stuck at the airport.
Their flights have been canceled and the airlines are working to get them home.
Plus they said most of the places they went to eat at was junk. Overpriced and one buffet they went to seemed to have food that was either from the day before or sitting under the heat lamp too long.
Moral of the story: Don't eat at buffets since visitor count is down, the food will not be refreshed as often. 
I tried the MGM buffet years ago, and I was completely underwhelmed. Seemed most were there for the crab legs, which meant a 20-30 minute wait for yours if the Fuller Family put their order in ahead of you. The rest of the food was so-so, nothing to write home about. The price back then was not cheap, so I'm guessing it's not gotten better.
The Main St Station had a wide variety, but again, the quality didn't blow my socks off. But, if you left hungry, it's your own fault. Cost was surprisingly high for downtown, but still affordable if you don't intend to eat again the rest of the day! I usually used a comp, and one time it was a New Year's Eve party i was invited to from The Cal.
The best IMO was the Fremont Hotel's Friday Seafood Buffet. Super variety, good to excellent quality, fresh and plentiful. Cost was a few bucks if you had the Boyd's food coupon. If not, it was still affordable and a great value. Comp's were made for these types of restaurants. You get to enter through a shorter line than the riffraff (

), and you get excellent service since the wait staff knows you're a preferred guest.
My problem is I'm not interested in eating until I'm in pain. So, the amount of food for my dollar isn't the great value it used to be.
i think it was Golden Gate, but might have been 4 Queens, where I went to ask about the buffet. They had stopped the buffet and turned it into kind of a cafeteria type thing. Go through the line, pick what you like, and they charge per item.
