Ohana's would be my choice - BAR NONE!
I love the peanut sauce at Ohana's and the taste of the steak and shrimp (my two favorites) dipped in the peanut sauce are just extrodinary!! I also love the banana bread and all the appetizers you get at the beginning. Then, just when you think you can't stuff another bite down your throat they bring you pineapple and caramel. Its dreamy!!
Last time I had dinner at 1900 Park Fare it was less than good. We haven't been back since.
Same thing with CRT. Last November we had dinner (again) at the castle and when we got done we just kept thinking how ordinary the meal was but yet the price is not ordinary at all. I'd rather go to Ohanás or Whispering Canyon. Although, it kills me that we aren't dining in the castle this year.
