Are you looking for emergency supplies, or everyday comfort items?

Thermos? Water bottles (full) instead.
Washcloth? Large bandana instead.
Spoon and Chopsticks? ??? What for?
Reusable shopping bag? ??? I guess OK if you're planning on shopping.

LesSnyder already mentioned a flashlight and whistle and mask.

Cellphone (even a retired one without a service plan will work for 911 calls)
Toilet paper (don't you just hate it when the stall is without?)
Fingernail clipper with file (I'm surprised how often I find this useful)
Anything for self defense is probably out for NYC, so no need to mention
