If you've never been to 'Ohana before, you will enjoy it.
Compared to visiting 'Ohana several times from 2005-2015, 'Ohana now is much poorer quality. It used to compare, in my opinion, to a Texas De Brazil or other nice steak restaurants like the Palm. 'Ohana now, in my opinion for dinner, is similar in quality to an Outback steakhouse, Texas Roadhouse, or Longhorn. Not bad, just not the same. Still an enjoyable experience.
I have eaten breakfast at 'Ohana twice since the beginning of COVID. Once before they brought characters back, with a 7:30AM reservation. It was wonderful and food was perfect! Another time at 11:30AM after characters had returned. Food tasted stale and was cold. Based off this, I imagine the later in the morning your reservation is, the more likely you are to receive food that's been sitting. Highly recommend visiting 'Ohana breakfast earlier in the morning.
