Delivery & Pickup Options – 440 reviews of Kau Kau Grill “BEST RIBS ON THE ISLAND. If you’ve had food from the Kau Kau Grill food truck, then you know what I’m talking about. This is the new storefront location in Mapunapuna which opened last month. It’s located in an industrial area near the new Fisher Hawaii. You need to look for it, on the Ewa/makai side of Mapunapuna and Mokumoa.
