We've had similar experiences at O'hana (we are generally a party of 2 or 3). The service is very uneven - bread and food coming before drinks, waiting forever for dessert and the check. I just chalk it down to the kind of chaotic nature of the restaurant (not an excuse, but after being there a few times, I kind of expect this). I'm sorry you had a bad experience with the service. Just wanted to note, if you were looking for a romantic anniversary type of dining experience at O'hana, yes, you're expectations were a bit too high, IMHO. After countless trips to WDW, we've determined the only way to get a stellar, quiet meal is to pick a resort, signature restaurant (and even then you have to be strategic - for instance, Jiko and Artist Point are quieter than Cali Grill). The only in-park restaurant that's ever been quiet or "romantic" in any way is Monsieur Paul. O'hana is all about large quantities of meat and coconut races!
