I think Nine Dragons is hard to peg because, more than any other cuisine, people's ideas of what 'good' or 'authentic' chinese vary so widely.
I don't know what 'authentic' is. And to me, 'good' is based on the quality of the ingredients, meats and vegetables, and whether the sauce seems gummy or not. (Based on that, I just had not good chinese in chinatown, so go figure.)
We actually like Nine Dragons. I think some of the more not common entrees are the better choices. If you order LoMein or Fried Rice, you're just as well off going to the mall.
My dd12 had the honey chicken, and declared it wonderful. The chicken was real, the coating was crispy and fresh and the sauce didn't taste plastic. I had the 5 flavor fish. While the fish was probably frozen, it was good, and the sauce for it was out of this world. I'd definately have that again!! Some of the dishes around me looked good, some not so great.
Anyway, if you're going for fried rice, don't bother. If you're going to try something different, it's not a bad choice.
