Gasho of Japan
I agree with what GIO said. Last time we were there, several years ago, the whole place smelled like wet dog. Horribly off-putting. However, I wonder if any renovations were required after that freak tornado last summer, as it touched down pretty much right where the restaurant is located.
I can heartily recommend Samurai in Croton (http://www.samuraisteakhouse.net/). They have both hibachi and regular table seating, are good to the community (donated gift certificates for a charity auction I worked on), and are also kid-friendly if that's what you are looking for. I am told the sushi is good, too, though I don't eat it.
Okinawa (http://www.okinawany.com) in Mt. Kisco also has hibachi, and the food is good. However, I find it to always be terribly crowded even with a reservation.

I have been to the one in Hawthorne several time but not recently. The last time was about 3 years ago and I swore it was the last time. At that time the place was not kept up, the bathrooms were filthy, and everything seemed to be in chaos. They have beautiful gardens out in the back but even those were not kept up. Instead of the serene Japanese music you expect to hear in those surroundings they had pop music playing. It was a disaster. As far as the food goes the quality had definitely gone downhill from what they had. I'd be interested in hearing if they have gotten back on track or not. Now there are so many of the Japanese Habachi restaurants in the area that you may want to try one of those, especially if they are new because I think the quality is always better in the beginning. There was one in Croton that opened about a year or 2 ago that was very good when we went but sorry I can't remember the name of it.....it started with an S.
I know you are asking about the one in Hawthorne but having been to both the one in Central Valley (we used to take field trips there when I was a kid) and the one in Hauppauge, I can guess the food would be similar in all. I found the presenation (the chef at the table) being the bigger appeal than the actual food. Better quality than Benihana but similiar taste. I never walked out of one saying "that was lousy" but on the other hand, never walked out raving about the food. It's a fun place for large groups, especially with kids.
