I'm flying up for some training on August 6th through the 9th and will be staying at the Millenium Hilton near the WTC. What are some great places to eat that are near by? Any recommended areas to check out?

My gf was able to take some time off so she'll be flying up with me. I've been up there before but she hasn't so we're obviously going to Times Square, WTC, Chinatown, etc. Recommend me some places.
