We went during happy hour and it was great! We got the big bowl of shrimp tempura for $10, kobe beef skewers for $10, kobe beef potstickers for $10, and the short rib dumplings for $8. I also wanted to try a sushi roll so I got the surf and turf roll and it was decent, but not the best... More

Sushi is expensive, at least the good stuff it is. And this wasn't that cheap, but it was certainly cheaper. Split about 6 rolls with friends, had a cocktail, and only paid 37.00. The food was amazing, so much so that I needed to order more, just because it was so good! If you are near Planet Hollywood and want... More

Great atmosphere, large restaurant with bar overlooking the casino at PH. The tuna with crispy rice was a great appetizer. Our rolls were wonderful. The sake selection is amazing.

We shared a series of small plates with 2 other couples. The tastes were great and it was a fun evening. The server did a great job.

We were very pleasantly surprised by the quality of the food. It's mainly a Japanese menu with some fusion items. I ordered some hand rolls that are not as aesthetically pleasing as the ones in a more traditional Japanese restaurant but the taste was good. My partner ordered the cod and he was very happy with his selection. I had... More

My husband and I have been to several upscale Chinese and Thai restaurants but Japanese was a first for us. This is partially because he doesn't care for seafood or beef, but the red miso chicken was a big hit with him. I personally loved the miso bronzed black cod. We also had the Kobe potstickers, which were fine, and... More

We selected this restaurant because someone at home recommended it to me before our vacation. We made reservations about a month ago but was probably unnecessary because we went to dinner at 5:30, when it opened, so we didn't miss our show. We were only the 2nd table in the restaurant at the time. People don't eat early in Vegas.... More
