My sister and I were able to get in and out of Nine Dragon in about an hour (possibly an hour and a half I don't remember exactly how long it was), so you should be okay. We like to take our time eating, so we were scrambling to get paid and outside in time for illuminations (and missed a little because of that, but we could see from where we were seated anyhow). But if you don't dine at the a real slow pace you should be okay.
