Had to put in another plug for Kona. We've eaten at MANY restaurants in DW, and our meal at Kona in September ranks up there with the most memorable. The atmosphere is pleasant, but casual. Everything we ate was delicious. My coconut chicken was perfectly cooked, and the salad that accompanied it was out of this world (I ate every morsel)!!! Save room for dessert; it's really a treat to visit the dessert bar, but difficult to choose only one! We will definitely return! (Sorry, we haven't been to O'hanas for dinner, so I can't comment on that. Based on the many reviews, it sounds to me like the food at Kona is a little finer.)
