I've had breakfast at both places and Kona lost my support.
Our server was awful, she let our drinks run dry and never stopped at the table to ask how the food was. I also wasn't impressed with the food because I didn't get the variety like I do at 'Ohana's. I ordered one breakfast item off the menu at Kona because that's all I would be able to eat anyway, but at 'Ohana's I get a variety of food like eggs, bacon, mickey waffles, fruit, and biscuits among other things. I also prefer 'Ohana's view/atmosphere, and maybe I like 'Ohana's more because I am definitely a character meal person.
