Fav art bookstore in the city (and the world?). Great place for inspiration and reference art, both new and vintage finds. Not very cheap but mostly quite worth it.
My favorite Japanese restaurant in NY...Small and cozy place, the staff is great, the food always simple and delicious, the uni shots are addictive and the sake perfect.
The best place to see a dramatic sunset is right by Valentino Pier in my neighborhood of Red Hook, Brooklyn. This was right after a storm. It's wild and brilliant and peaceful all at once.
