Once New Amsterdam
Great city, tons of history, so many things to see and do. Definitely recommend taking the road less traveled, that's how I ended up with my flat cap that I bought in Harlem and eating a delicious lamp stew from a stall at a weekend market at Union Square in lower Manhattan. The city is almost bursting from the endless possibilities.
Insider Tip:Walk, limit the use of the subway system. I do not know how many places, people, and events I found just by randomly wandering about.
