A. Even if you are not staying at the Mandarin Oriental, visit MOZen, it is excellent.
B. The service was phenomenal. Our waiters, Steve (a great resource for all that is Vegas and a man who knows his sake) and Alex (new to the game but eager to help) did a great job taking care of us.
C. Go with the Bento Box, you will not be disappointed. It is a filling variety of what MO has to offer and keeps things light if you are about to hit the town.
D. Their sake list was out of this world and reasonable. Cheaper than what we pay for at high end places in Texas.
E. Excellent, fresh sashimi.
If you have the time, perhaps to just check out the MO or spend an evening around City Center, go and enjoy an intimate dinner at MOZen. It is well worth it.
