The New York Earth Room is an interior sculpture by the artist Walter de Maria that has been installed in a loft at 141 Wooster Street since 1977. Go see!
Wonderful place to grab a coffee+pastry with a great vibe and outdoor-only seating. Best cold-brew in the neighborhood. Doubles as the headquarters for The Lot Radio station, so there is often a live DJ spinning pretty chill music.
The rooftop garden at the Metropolitan Museum of Art. The museum floors below are a maze of tremendous art and inspiration, and taking the elevator to the rooftop garden is the icing on the cake. 360' views of verdant green Central Park bordered by cool glass and steel of Manhattan's cityscape in the distance.
