Where's the best place to for lunch if you're in the mood for inexpensive Japanese food? Minato Japanese Restaurant in Moiliili.
Part of what allows them to keep their lunches at a low price is that you order and pay up front, pour your own water, and set your own table. But, they do bring out your food for you, and they clear your table once you're done eating.
