Hawaii is such a nice place to relax and unwind. I hope you have fun there. If you are close to these places, I highly recommend them:

Tanuki Sushi - Good Japanese food, for reasonable prices. We requested the Omakase to try the different sushi available. Their Uni is really good.

Bar Maze - A unique dinner course experience where they partner their food with mixed drinks.

Bar Leather Apron - If you want to have more of the mixed drinks, this place is really good. It's reservation only, but I think it's worth it.

The last 2 are difficult with kids since they might not appreciate the food, as well as they're too young to drink. If you have others with you to look after the kids, and you want a nice dinner/drink with your partner, those are good locations.
