If you want authentic Japanese cuisine, this is the place to go.
That being said, don't expect the standard sushi roll, teriyaki mystery meat, "eedamamee" (it's eh-da-mah-meh by the way) fare.
Best thing going on here, like some of the previous reviewers have mentioned, is their teishoku sets. Although they have daily/weekly special sets, I would have to say that their yakizakana (grilled fish) teishoku is their signature item. Reasonably priced and absolutely delicious.
My only problems with this place are...
1.) They seem to run out of supplies/ingredients early (yeah, we just opened for dinner, but we're already out of [fill in the blank]) and the fact that they don't actually grill their fish (they probably broil it). The problem with broiled fish is that the natural oils in the fish don't "drop" out as they normally would in grilling, leaving the fish very oily.
2.) The servers try too hard to speak in English. Yeah, I can understand that most or if not all of them are here on a work visa to learn English, but I've noticed that Japanese women sound very butch when they speak in English (when it's not their first language). Also, the etiquette standards that you would expect from any restaurant get lost in translation some how and the servers are a little too informal. Since it's a Japanese restaurant, I'd rather be greeted with the traditional/standard "Irashaimase!" than a "Hey, Guys!"
3.) The levels of service are not consistent. I've gone on some nights where I've had an absolutely wonderful dinner and I've gone on other nights wondering what the hell is going on. And it has nothing to do with whether or not they're busy. I've been in there all by myself and had lousy service and I've been in there when it's absolutely packed with a line out the door and had terrific service. I just don't understand the inconsistency. There's only so many seats in that place that being busy or not really shouldn't affect the quality of service and "not having enough staff" can't be used as an excuse.
