Citricos is also very good but we've personally been disappointed by their seeming inability to change anything on their menu in the last two years since we've last dined there. A little variety goes a long way, especially at a signature restaurant.
Citricos did make one change in the last two years, that I didn't like. They removed the berry gratin from their dessert menu. I'd go to Citricos just for their gateau of crab and berry gratin. I've never been that impressed with any of their entrees though and agree they need to change the menu up some. Their pork loin and short rib were OK. I was not impressed with their steak either (overcooked and tough).
To OP: I'd go with Flying Fish. They are the only Signature restaurant that has an appetizer, entree,
and dessert all that I love (tomato/mozzarella salad or mussels for appetizer, scallops with risotto for an entree, and chocolate trio for dessert with a glass of ice wine

). Their steak is also very good.
Artist Point would be my second choice, just because there are selections on their menu that you can't get everywhere. We like their mussels or mushroom soup for appetizers and buffalo strip for entrees. They used to have a good berry cobbler, but when we were there in Dec they had changed it up (less berries and much smaller, plus had a yucky amaretto ice cream on it, instead of the usual black raspberry) and we were not impressed with it. None of their other desserts have ever impressed us. Narcoosee is OK and a great deal if you are on the
DDP. I have not been impressed with their steak and lobster, so usually have them substitute scallops for the lobster. You get a full order of their scallops, plus the twin filet medallions. I do love their almond cheesecake though. I am not a picky eater, but the one thing I found I did not like at all at Narcoosee was their tomato/mozzarella appetizer. I don't know what that foamy lime green stuff on top of it was, but I didn't like it and sent it back almost untouched.
