Hi, I saw your question and couldn't help but jump to respond. I am a Las Vegas local and I have stayed at the Plaza twice now since their renovation. It is a great hotel and one of the best values in Las Vegas. The room renovation is very nice. They gutted everything except for the bathroom door (which is bizarre). The room has a very nice fresh clean look to it. As for the casino, it has been completely gutted. They have a ton of new food outlets. Everything from a full fast food court with Subway, McDonalds, coffee shop, etc. to great restaurants such as Hash House A Go Go, Island Sushi (my favorite), and the former Mayor Oscar Goodman's steakhouse. It is a great location with a perfect view of Fremont Street.
A couple words of caution, if you get a room facing Fremont Street you will hear loud music playing until around 3am, so if you plan on going to sleep early this is not the room for you despite the view. It you want something quiet get something in the South Tower, not the North Tower. Also, the wall are very thin, so be careful about having a loud conversation if you want privacy.
