Dang it, I forgot that your D7000 is a DX body. I think your 18-55mm lens can handle the wide shots. It's just that the 24-70mm is tack sharp even at f/2.8 so you can take all the money shots with that but the problem is you can only go as wide as a 36mm on the lowest end.
Sahil, you can get some nice website ideas and photos on these links:

you can also google "best restaurants in nyc" and then click on each individual resto's website so you can pick and select the best images from each of them.
