From that list Flying Fish and Topolino have been on POINT! Citricos was in our top 3 last trip in November also. Jiko is awesome as always. California Grill RIP for our family since they reimagined it years ago. Just won't do it again. Hate on me but just my opinion. You mention duck. Morimoto has duck. No one will share it with me in my family so I never had it but talked to a local couple next to us last trip who goes for it once a week I guess. lol It does look good. My grandmother always made me duck growing up. Narcossee's another one where you can't go wrong.
If our kids like duck I think you should give that a try. It's not a "fancy" place compared t some of the others mentioned but our meals are always good.
I think right now Topolino, Flying Fish, and Citricos are the best most consistent "fancier" places for our family.
Il Mulino is always good too. Pretty consistent.
