We love both options food-wise. On the basis of only food, I would say Ohana, just cause it's different than what you would get in most places, and generally good quality. For service, however, we have had poor luck with Ohana, and have had great staff with LTT every time we have been. Also, kinda depends on time of night. If you are wanting something late in the evening, Ohana is nice in that you can possibly watch the MK fireworks while you eat.
