I've always just driven past this hotel to and from The Strip, but finally we decided to stop at The M Resort to try the infamous Studio B Buffet (http://www.yelp.com/biz/studio-b-buffet-henderson#hrid:YqQFE3mvYVzfkfYzVeXaxA).
This hotel is absolutely gorgeous! The decor is phenomenal! The design is modern and the casino floor is very spacious. I'd recommend definitely checking this resort out sometime.
I'd be interested to, but probably would never stay here because it is too far away from The Strip for my taste. However, I will definitely be back for their restaurants... particularly the buffet!
