We need more information to give you appropriate recommendations.
What type of food do you like, how much do you want to spend (be specific, rather than saying moderate priced, for example. Your idea of moderate may be different then what's considered moderate in New York. Also keep in mind that you'll pay almost 9% tax and 18-20% tip)
Any preference for specific neighborhoods? How far are you willing to travel?
The more specific you can get, the better advice you'll get.
