Hubs and I have been going here for years. We love it. The food is totally yummy. It's a bit different than the other Hawaiian food restaurants I've been to. I don't normally enjoy Hawaiian at places like Aloha Kitchen. Moki's is more flavorful and less... mysterious. I like being able to tell what it is I'm putting in my mouth.
The atmosphere is kitschy-cool and I love the surfboard that acts as lighting. Yeah, you read that right. Also, the drum by the door to let them know the food was good is clever and fun and definitely adds to the Pacific-Island feel.
I have used them for corporate catering purposes in the past to great satisfaction. All parties who ate the catering raved and asked where they could go to get more. Everyone is great to work with and the prices are great too.
