I was a server as well, (Back when we were called "waitresses") and therefore I tend to give a pass to restaurants that seem to be having an off night. I also watch to see why, if possibel. The last visit to 'Ohana, and it was or LAST, I observed a manager holding the wall behind us up as he leaned on it for a solid two hours. Yep, we were stuck in that madhouse for over two hours while our poor server did her best to hide from the savages seated next to us. He never once stepped in to assist her, or to at least protect her or us from the bedlam that was ensuing there.
The drinks were horrific, and when we asked to send one back we were told it was supposed to taste like that. Hmmmm,, then please remove it from the bill.
The food was mostly cold, and the meat was dry and stringy.
'Ohana has a lot of up and down reviews, and the negative ones it may be from any one of those concerns you list, however for those of us who had made it a point to visit very trip, and who are okay with an off night to a point, we can see the changes that have taken place over the past several years. This was always a pretty popular restaurant, but it was not an impossible one to book. There was always a bit of a wait, but it never ran as far behind as it is running now. The food was sometimes served in a haphazard manner, however it was never "gross" "cold" or dried out. It seems to me that something internal has changed, and I am willing to bet our farm that it began with overbooking the restaurant to accomodate all those guests clamoring to dine there, which led to the kitchen "prepping" food in advance. Now the line backs up earlier, servers are encouraged to rush the meal, and the kitchen is working the food to have it ready to push.
My dad was a chef. I recognize when meats are prepped in advance, and when food is kept under a light, or warming. Our reality that last night was that our foods was cooked in advance and finished for service, our server was way overworked and undersupported by management, and our drinks were just tossed together by a very busy bar staff. I have had an "off" night at 'Ohana, but never a debacle like that evening.
That happen to one of our party on that fateful last evening. I heard from a few of our crew that they were "ill" however I was not sure if it was the food or just them. I have a cast iron stomach, and I was fine.
