Coffee. Before the chains of interchangeable multinational beverage shops became ubiquitous in New York, there used to be little places that served what they described as coffee. Not 'latte' or 'cappuccino' or 'grande soya de-caff mocha' but its straightforward, unadorned cousin. Your choices were, black or white, sugar or not. Sometimes it was great, sometimes it was battery acid but it was honest either way.
Day 3 - A good cup of coffee at Cafe Gitane on Jane Street. At some point in the drinking you get a little skyline appearing from the caffein 'Hudson'. There are still lots of places if you look a bit.
