Jess: when the weather warms up a bit, I recommend Bryant Park–it’s even a wifi hotspot (http://www.bryantpark.org/amenities/wireless.php). Excellent access to the ‘wichcraft kiosks and the Treats Truck lady is close at hand at 38th and 5th on most weekdays. Other midtown park your laptop picks…the concourse at Grand Central–I kind of like the hustle and bustle of it all–or there are a few odd little outdoor “plazas” in midtown. There’s one that I like that cuts through the middle of the block between 5th avenue and 6th avenue, you can access it from 45th or 46th street. I’ll sometimes get something from Kwik Meal or the Biriyani Cart and enjoy the sunshine there.
