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.
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.
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.
