This stone is from SoHo. For this area I would recommend skipping the big flagship stores on Broadway and ducking into the side streets instead. That is where you will find the iconic cast iron architecture and those hidden boutiques.
Even though it is a shopping mecca the real vibe is in the cobblestone alleys. If you need a break I highly recommend grabbing a coffee at ansa Micro Coffee Roastery while you explore.
It is the best place for a long walk if you want to feel that classic and artistic New York aesthetic without the usual crowds of the main street.
