Oh bless your heart for posting those pictures! Especially of the shrimp tempura roll, my very favorite!!!
Can I ask you, did you use dining plan at all for that sushi platter or was it all OOP?
Meanwhile, on to the OP's question: I think it depends upon your level of committment, if that makes any sense. Like if you want to be in a more upscale atmosphere, go with Cali. But if you just want a casual, walk-up experience, the Kona bar is the way to go. Either way, YUM!!!!!!!
