We gave MM a try about a year ago. My husband had his heart set on the cookbook tasting menu with wine pairing, which will set you back about $170! I decided to be different and ordered a trio of heirloom tomatoes (awesome) and the miso cod (delicious...not as big of a portion as I would have liked) as my entree.
My husband was kind of enough to let me taste all of his 5 courses as well. The tuna tartare was amazing, and the lobster pot pie was very good! It was a bit on the heavy side, so one bite was just enough. They did give him a sampling of the premium wine pairing, in which he wouldn't stop talking about this white burgundy, like he was going to take it home or something ; )
The restaurant was much brighter than most of the restaurants we have been to in Vegas. Service was spot on, and our table was very nice and private.
MM has a lot of competition located in the Bellagio, however, it is a great restaurant that should not be overlooked.
