Without knowing the dynamics of your party, I would say skip Jiko. I have eaten at all four and would go back to all of them, but Jiko was my least favorite. Some of that has to do with location and transportation issues. Unless you are staying at AKL, it was either a really long bus to bus trip or a cab ride. I actually like Boma better!
Cali grill location, view and food are great! Yachtsman - good wine list and great steaks! Narcoossee's has nice atmosphere and good food without being too stuffy.
