On our trip in July we went to all 3 - Boma, Ohana and Yak & Yeti - and while all 3 are good, I would skip Yak&Yeti. We made the mistake of eating at Yak&Yeti's Counter Service for lunch that same day and our cs meals were very similar, and very good, as what we had for dinner. Ohana the kids will loooove. My boys were hardly at the table they were too busy joining the parade, playing drums, doing the limbo and all the other shenanigans they get the kids involved in. When we were there there was a large table of policemen and their families celebrating and they recruited two of the officers to lead the kids in the parade and limbo. They wore coconut bras and grass skirts- it was hilarious. And, I'm sorry, but the food is awesome! I am not a chicken wing lover but theirs are yummy! The meats are delicious (it's the marinades!!!) and the noodles were nothing to balk at. And the dessert? Goodgraciousalmighty, is it goooooooood!!!

And you get about 3 pounds of it. You and your dh will pretty much enjoy a meal to yourselves while the kids play.
But I can also go on and on about Boma too. It is unique foods but your kids should be fine with the kids selections. The dessert bar is fabulous and who would think I could love a food called "pap" as much as I did! Yummy! Not to mention it's a good excuse to see AKL.
Yak&Yeti table service...it was good. Not out of this world and there's nothing especially great about it. It's a beautiful restaurant but service seems to be slow. I did love my meal though. Desserts are just eh, ok.
