We just ate at both places and I would opt for O'Hana's. Both have fun events for kids. WL serves salad, mashed potatoes, corn on the cob, pulled pork, BBQ ribs, chicken and sausage. O'Hana is veg stir fry, shrimp wontons, salad, chicken wings, rice and grilled turkey breast, steak, pork and jumbo shrimp (prawns).
The reason I opt for O'Hana besides my love for shrimp is that it is more quiet. Honestly, you can hardly carry on a conversation in WC, especially during peak dinner hours 5-8. We had a great waitress and the food was good but it's not relaxing.
