Great meal, but very pricey. If you are looking to impress your guests or go all out, definitely check out Kumi.
Our group of 9 ordered the Omakase menu (chef's choice). I don't recall everything we ate, but I can definitely say that everything I put in my mouth that night was delicious. The tuna and hamachi were particularly tasty.
In typical Vegas fashion, the ambiance is was seductive and the waitstaff attractive.
Fortunately this extravagant meal was a company treat, because with booze and bottled water, our bill came out to around $1600. Yikes!
TIP: The bathroom doors don't lock well, so you might want to have a look-out! Others in my party had the same issue and I saw a few other people getting walked in on as well. Oh, and I don't believe the bathrooms were segregated by gender... have fun!
