Hi, we were at O'Hanas last month. I think it's a great place for kids. We did not have ours (teens), but the 4 kids at the table next to ours had a blast. They were approx. 4-8 years in range. They got up and played the hula hoop and other games. This is great as you know how kids don't like to sit for a long time.
My DD has been twice (ages 4 & 5) and will be going again this year. We all love this place and there are plenty of things for the kids to eat and lots of fun games as well. I think the ages of your kids would be perfect for this fun place. Enjoy - the food is wonderful!!
