I hate to disagree with those that say to go to both, but I feel the need to share our experience. We ate at 'Ohana last time based on the overwhelmingly positive views on this board and really weren't that impressed. We made a reservation late so that we could see Wishes as suggested. It was a mistake.
First of all, they were running late. Like 40 minutes.
Second, our service was horrible. We rarely complain, but we actually insisted on seeing a manager it was so bad. Beyond the bad service, the manager was rude.
We also did not get a view of Wishes as we had hoped. It's understandable, of course, but don't go planning on it working out that way.
And finally, we thought the food was only so-so and delivery was slow. I'm sure it is because the restaurant was packed, but the night would have been better if the food we waiting endlessly to recieve would have been good.
So...as you can imagine, we are not going back this year. We're headed to Kona instead. If you do end up going to 'Ohana, I hope you have a better experience than we did! It seems like others have better experiences, but this was ours.
