    Great Place. Great service. Good meeting place. A few different places to enjoy a cocktail after dinner at the Four Seasons. Or enjoy the Art Gallery above the Spa area.

    Wonderful service - the waiter knew all the details about the menu, including wine list. Offered help only when asked. Couldn't have been better.

    Tried almost every nigiri on the menu, most were a bit fishier than normal. Hand rolls overloaded with rice. Rice quality not the best I've had.

    The food was great, not the normal portions size, so extra was order. Overall, the food was fantastic packed with flavor! Have not had ramen in a really long time and ordered it here, and it brought back childhood memories, I will be ordering it again. Wide loved the waygu beef and pork belly hit the second order was needed along with the beef skewers.. The service was awesome and the staff was super pleasant!

    First off the valet at the hotel are very friendly. The wait staff at the restaurant is top notch and very friendly and understanding. We had staff check in on us no less that 6 times while we were there and it made us feel very comfortable and important. The food was a knockout, the fish was melt in your mouth creamy and the drinks were great as well. The ambiance was sublime, we sat outside in the courtyard with a view of the waterfall and the trees, it was serene and tranquil. Value for the food was also amazing. All in all a fantastic restaurant for a semi formal date or a business party. 10/10 WILL recommend

    We were disappointed. The wagyu was fatty and tough and the seabass was crunchy and dry. The manager was very attentive though and took off our bill but our expectations on food quality were not met at the level we expected.
