I just got back (from the Marriott) and now Grub Hub delivers to Ko Olina! OMG what a convenience! We ordered from Sushi Bay twice, and Pearl’s Korean BBQ once (but ordered a ton so had 3 meals). I highly recommend Pearl’s if you like grilled chicken and beef (the spicy chicken was the favorite). It’s not expensive, and the portions are generous! They also have mandoo (dumplings), yum.
We did have to meet the driver at the front, but easy for my DH to run over and get it while we ate at the pool one afternoon. Nice when you’ve had a couple drinks at the pool, so don’t want to drive.
Just throwing that out as an option. Pearl’s has large orders of BBQ meats that can be shared family style, plus rice and veggies.
