We just got back on Friday, and we did both.
I'm not even a big meat eater, but I love Ohana for the sides,the salad, and the dipping sauces. The beef was very good.
Kona is calmer, amazing bread (OMG!), and I loved my shrimp and scallops. The kids got the Kona Cloud for dessert, so that was a thrill.
I WANNA GO BACK !!!!
