My rankings of the signatures are: Flying Fish, Citricos, Jiko, Ca Grill, HBBD, Yachtsman, Artist Point, and then Narcoosees. We have eaten at all of these several times, all at least once within the past 16 months.
I think the top 3 have the best food variety. I love the food at FF but it's pretty noisy there. Citricos at Jiko have good food and usually a quieter atmosphere. Service has always been top notch. Ca Grill has very good sushi and a breathtaking view but I've never been overly impressed with the other food options there and it's an incredibly noisy place to dine. HBBD has some outstanding choices and then some very mediocre choices. Yachtsman has good filets but I've been disappointed with every other cut of meat I've had here. I enjoy the appetizers, bread and desserts here though. Artist Point and Narcoosees are at the bottom of the list. AP has good food but the menu is heavy for my taste and the decor there is a turnoff for me. Narcoosees used to be wonderful but we've been very disappointed on every visit for the past 10 years.
