When at O'Hana...they will bring you as many seconds, thirds, fouths, fifths, as you want! That is my hubby's favorite meal. AND...he loves the bread pudding. I think if he could...he would eat the bread pudding all night.
When we first had it a few years ago, it looked like it could feed 8 people. We never did finish it. However, I have noticed that it has gotten smaller. On our last visit, I was positive we would have to ask for more. My whole family loves it. But, we were too full and only ate a few bites. My husband was positive he would be eating more, but couldn't. I think it's more than it looks.
But they will bring you more if you ask. I'm sure many people do. Our waiter asked if we wanted him to bring two and we said, we'll see how this is and then we'll ask for more. Then he came back with tons of ice cream for the kids. I think it was 5-6 large scoops and we just stared at it. My husband on the other hand took a scoop and couldn't eat more.
