People tend to check in during these times:
Best boneless chicken in Honolulu
Came after the lunch rush (1:00pm) and the lady behind the counter was very nice. Nothing fancy here, just plain good food.
Hawaiian plate on Fridays
The.loco moco with fried rice is the best.
They have the best boneless chicken on the island!
To even further expand on the grouchy lady, have your $ ready to go along with your order. If you take too long she will breathe heavy and give you stink eye.
This is a hugely popular lunch spot downtown for plate lunches. Come early if you want to get in on the daily specials. Wait to late and they'll be sold out.
Roast pork with stuffing and gravy is ono here.
Fridays Hawaiian plates are good and won't break the bank
To expand on Anthony's tip; the lady at the register is like the Soup Nazi. Know what you want to order when you reach her, be sure you say what size (mini/reg) & if you want white or brown rice.
Don't come to the front without an order in mind, the woman will give you stink attitude.
