I have been to alot of Las Vegas buffets in my time (an nowadays, pretty much every hotel offers one). But up until this day, the Studio B buffet at the M Hotel has been the best one by far!
First, it's not overpriced like the Cosmopolitan Buffet where you are paying $70 for 2 people! It's about $50 AND you get complimentary beer and wine. Other places will charge you separately for alcohol. Another thing that sets them apart is the quality of their food and their selection. They have a variety of exotic salads and every dish from every corner of the globe offered was fresh and tasted great. On top of that, their staffs' customer service was top notch.
The overall dining experience was awesome. I would recommend any person visiting Las Vegas to come and eat here!
