I agree with Robert S that they shouldn't try to pass themselves off as a hip restaurant, because it really isn't. Although it's in a good downtown location (at Harbor Steps at 1st and Seneca), it reminds me more of a mom-and-pops shop in Little Tokyo. They have a wide variety of meals - lot of it standard fare. We were in a temporary housing next door (Harbor Steps Apts) for a while so we ate there a few times, and the only complaint is that my fiance got sick after he ate their tonkotsu ramen (he commented it tasted funny too before he got sick). It could be the cured pork, chashu (different spelling in Chinese, which I don't know - sorry), was old. Also tonkotsu takes the soup stock from pig bones, so that may not have been cleaned well.
It's nice to have a comfort food restaurant, though, which has things like katsu-don (fried cutlet cooked in eggs and dashi on a bed of rice) and oyako-don (chicken and eggs cooked in dashi over a bed of rice; since chicken and eggs are parent and child it's called oyako - parent/child - the variation is tanin-don, which translates to stranger-bowl, if you use beef and egg - ha ha). Having cheap-ish udon and soba is also nice.
In summary, I wouldn't go there for a particular reason or a date, and probably wouldn't eat sushi there, but if you're a nearby and miss some home cooking style Japanese, this place would probably come out cheaper than a lot of places around there. And yes, the chef and at least one of the servers are Japanese. But it's common for Japanese restaurants to have more unskilled labor in the kitchen, so I wouldn't count on delicate Japanese cuisine - but at least it's being supervised by Japanese so it wouldn't be terribly unauthentic.
