Also in agreement here... we (wife, 2 college age daughters, and I) were at both about a month ago. We enjoyed both very much... we talked about 'Ohana a lot after we ate there (doing Lilo & Stitch takeoffs... we said things like... 'Ohana mean I can't eat anything else, etc.)... we loved it... as you can tell, we ate too much delicious food.... save room for the pineapple and caramel dipping sauce (no need to buy desert!)...
We also like 1900 Park.... but for different reasons... big variety of food and character interaction....
We had excellent servers at both places...
I agree with other posters... If you are looking for a serious or romantic meal... these are not the places (no slam... just not they atmosphere they want to project)... If it's just a bunch of adults getting together for a good relaxing time... I don't think you could beat 'Ohana... for something a little calmer and character fun... 1900 Park is very nice (try the bread pudding... mmm)
let us know what you decide... I was there 10 days... I ate lots of places if I can be of any help.... Liberty Tree Tavern was a lot of fun too... in a nice colonial setting with characters.
