    They were out of a bunch of stuff on the menu including all sashimi, nigiri and all salmon. Not a very stocked sushi restaurant. Crispy rice not crispy. Spicy tuna not spicy. Kinda frustrating. Otherwise the service and ambiance were great. Food not fantastic just okay.

    Very small menu. Expected a lot more options. Quality of my surf and turf roll was mediocre…even the rice was a strange texture. Service was great, but wouldn’t recommend this spot…one and done for me.

    They had about 1/3 of their menu due to “supply chain” issues including no tuna, cod or at least one of the ingredients necessary to make fried rice. They must have had regular white rice though since we got charged for it. Also didn’t enjoy how the waiter helpfully “offered” us an extra piece of two appetizers and then charged us for it. I thought it was to compensate for the lack of menu items. We didn’t need or request it. If you plan to eat here soon, I’d call to ask if they have their full menu or be prepared to go somewhere else in Mandalay Bay that does.

    Food was mediocre. Service just ok but very noisy in restaurant. Sauce on goyza ruined the flavor-if you get it ask for sauce on the side.

    The owner ads a 5% operations fee charge to the final bill so be careful because it is not disclosed anywhere on the menu and you have to ask the waiter to take it off manually so they be scamming there

    We have eaten here in previous years but were really disappointed on our return. The menu had shrunk right down to what the manager agreed was pretty well a Happy Hour menu. The service was poor, the food tasty but expensive, and nobody was able to tell me what the $6.50 operation fee was actually for. Relatively minor but it added to the feeling that we had been ripped off

    The kitchen was bare and there was no wine list. Waitress was awesome but was under pressure as she had nothing to offer food wise. We had a choice of very few things. Japanese restaurant with no sushi?

    This was a disappointing meal. The server was curt and unapologetic when he told us that they were out of many of the vegetarian items on the menu. The food that was available was OK but not great. I wouldn't bother to go back there.
