My girlfriend and I did both this past May. RR was ok, not great but not awful. I thought the accoustics in the restaurant were pretty bad and the music sounded pretty muffled but was still pretty good. The food was ok for what it was, but the quality and execution could have been better. I liked the bread pudding better here.
We found 'Ohana to be an all around awful experience. Our waiter was horrible, the meats and poultry were so dry that not even the sauces could help, the other food tasted like it was out of the freezer section of a supermarket (and then the directions on the package were ignored), the "entertainment" for the kids was obnoxious and annoying to say the least. Long story short, not even a nice view of Wishes from our table and a great chef who came to talk to my girlfriend about her food allergy options (peanuts/treenuts) could convince us to give it another try.
In general, for every positive review you read, you can find a negative review. We always find it better to go out and form your own opinion. We are also the types who like to try new things, so we would suggest giving RR a try.
