    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.
