You may also want to check out Chelsea Market
. If you walk down High Line park on the West side, High Line terminates at Chelsea Market. You can take in nice views of Manhattan from High Line and have a nice eating/shopping experience at Chelsea Market.
If you want to walk down 5th Avenue to 14th Street at Union Square, there's one of the greatest Farmer's Markets that you will see anywhere. Union Square Farmer's Market
There's a huge selection of breads, jellies, meats, veggies. Incredible to see. Garden of Eden
is right around the corner at 7 East 14th Street. It's a deli that has nice prepared foods. There are no tables in Garden of Eden so you'll have to take a stroll to the park and have lunch there.. if it's not too cold, of course.
