How do you get from Penn Station to Ninja NY by subway?

Ninja NY is at 25 Hudson Street, between Reade and Duane Streets. Take the Downtown 2 or 3 express trains (of the 1-2-3, the red line), 2 stops, from 34th Street-Penn Station to Chambers Street.

You will exit the subway at the 3-way intersection of Chambers Street, West Broadway, and Hudson Street. Walk 1.5 blocks north on Hudson Street (north is the only direction you can go, since Hudson Street begins/ends here) to 25 Hudson Street between Reade and Duane Streets.
