We've eaten at the following signature restaurants several times... here are my ratings:
Jiko - A+ for food quality, A+ for service, B for atmosphere. We continue to be impressed by the unique variety of dishes offered here. Our meals here are the most memorable and the staff leaves you feeling pampered. I wish there was a nice view from the restaurant.
Artist Point - A for food quality, A+ for service, A for atmosphere. We love certain dishes here, but the menu leans a bit to "run of the mill" variety. I might rate it higher if I weren't allergic to fish - my family loves their cedar plank salmon. We love the peaceful setting and the attentive service. This was our favorite for several years, but the food at Jiko has moved this long-time favorite to second place.
Citrico's - A- for food quality, A for service, B for atmosphere.
California Grill - B for food quality, A for service, - the atmosphere rating will depend on what you like.... the view is A++, but it is a noisy room, so if you like a quiet, romantic meal....B-.
