A great buffet but pretty far off the strip. Its a good thing that the M resort itself is a fun place to be.
So we stood in line for about 1 hour 30 min when it was estimated a 2 hour wait which is good. Oysters and crab legs are always excellent, but what sets the crab legs apart are the fact that they are served whole. Some places like the Wynn buffet will split in 1/2 for you, really killing some of the taste.
Beer and Wine being served make it awesome, but you should try the root beer that they have on tap too.
Other than that, most Vegas buffet items are available, although I didn't see if they had anything made with Kobe Beef.
The Best Buffet in Vegas? Probably, but not by much. For the $30 you can find other great meals in Vegas.
