My husband really didn't care for it. Of all the restaurants we've been to, this is the one he always mentions as his least favorite. He felt that the food was marginal, at best, and the atmosphere didn't impress him. I thought it was fun, and I enjoyed it, but had to agree that it didn't live up to my expectations.
Also, I was told that I had to order a meal for my 18 month old, which surprised me because all he ate was a handful of rice. He was still drinking a bottle at the time, (not as his main meal but something he would normally drink late in the evening.) Our dinner was at 7:00, which was late for him, so I fed him a small meal at 5:00 when he was hungry, and we brought his bottle to 'Ohana for him to have while the rest of us ate our dinner. (DH, DS3 & myself.) The CM insisted that we had to pay for him as well, so essentially we paid $10 for my 18 month old to drink his own bottle at the table, plus eat a little bit of rice off of my plate! I was a little annoyed.
On second thought, now I'm liking 'Ohana even less.
