Las Vegas has a big islander community, so Hawaiian food is easy to come by. I've been to a bunch of different restaurants, and Ohana definitely stands out.
Price wise, it's similarly priced with other establishments of its kind. However, the servings seem a bit bigger than normal. I order the mini katsu (one of my favorite dishes), and can barely finish it. Don't get me wrong, your boy can eat. I've tried maybe 6 or so of their dishes, and have yet to be disappointed.
I haven't had a bad experience yet at this place. The service is always nice. They greet you when you come in and say goodbye when you walk out. Wait time for food is normal. A coworker and I have even recommended that our office have Ohana cater a luncheon, and the whole office loved their food.
