If you're interested in partaking in a traditional Hawaiian Luau, feel free to check out Paradise Cove. It is also in the Ko'olina area which is near the wedding venue and recommended hotels.
Nice lunch and dinner restaurant in the Ko'olina area (the strawberry pie is very good).
Casual breakfast spot in Kapolei. Order the pancake flight (mini Cookie Butta Luva, Lilikoi, & Chocolate Taro-haupia pancakes) and thank Maddie later. :)
Great beers on tap, casual bar food in the Ko'olina area.
One of the largest outdoor shopping malls in the country! Located on the east side of the island. On Saturday mornings there is a farmer's market across the street from the mall. :)
