It’s Koa Pancake House, but you were really close
There’s one in Kapolei, so it’s much closer to Aulani than Anna Millers and MAC 24/7 (both of which, imo, are just ok). Lots of locals love Koa Pancake House, myself included, and it can be hard to find a seat on the weekends so go early.
If you’re willing to drive 40-50 minutes, check out Kimo and Boots in Kailua. They don’t take reservations and there’s always a 30-60 minute wait, even on weekdays. Cinnamon’s guava chiffon pancakes are another local dish worth seeking out.
