As said by previous reviewer, this is a chinese run japanese place but I though the foods are quite decent. It's only across the road from my work so I do go there every now and then. I usually order one of the ramens. The serving is quite generous.
Approximate cost: $10
Japenese(run by Chineses) eat-in or take-away restaurant located in the food court of 530 Collins st. Food is pretty ordinary here...some of the sashimi(tuna) was so unfresh that I couldn't even swallow...miso soup was extremely salty...and everything else we had was pretty much of standard food-court quality.
