I enjoy a good bowl of udon and MM is a great addition to the Chinatown in LV. This place specializes in udon and when a place specializes in one main dish, chances are it's going be good, or at least better than other places that focus on a lot of different dishes. I visited a few times and I rate this place high.
We started with the Takoyaki appetizer. This is a favorite of mine. I've tried it in various times in festivals in Tokyo and the US. Some places have a good balance of flavors while some are overpowered by the sauce. MM gets it right with a good balance of flavors. However, depending on what udon you order, it may be better to have this while eating your udon or even after it. I'll explain later.
Our group then tried 3 udon dishes - beef, shrimp tempura, duck. I had the beef. They are served in big bowls so little chance of spilling while you work through it. The presentation is great. The taste is better. The broth is quite subtle and clean. I loved it. The noodles were good and cooked just right. I prefer cooking it another minute for added softness but that is my preference. The beef was flavorful and the portion was right. More than other places. You won't feel underfed.
Now back to the Takoyaki. Udon broth flavor is relatively light so if you order a shrimp tempura, it is a light flavored fare versus beef. Eating the Takoyaki starts your palette with a stronger flavor which can make your udon taste lighter than usual once you get to it. Some dishes may benefit from having the Takoyaki with it. Just make sure you taste the udon first.
The location is fine but parking can be tough on a Friday. There are tons of parking but not enough to support all the establishments. Expect to park farther or make a few rounds.
Overall, I highly recommend this place. I'm still working through the their menu and this place has become on of my favorites to visit in Chinatown.
