Since launching, the New York Restrooms map has grown exponentially and its open source format lets users just like you add new restrooms as they pop up, so, once you're done washing hands, be a good neighbor and let the public know where to go.

Restroom options are handily color-coded and broken down by location type, ranging from public restrooms to restrooms located inside hotels, fast-food joints, bookstores and coffee shops, plus a catchall "other" category. Click on a listing and you can see a Google Maps view of the location, plus locate some other handy info, like whether the spot is handicapped (or stroller) accessible, and if it's open.

The map works beautifully on a smartphone, too, so be sure to add it to your bookmarks. While some businesses may require you to purchase something, I've never seen a potty-dancing kid be turned away, nor one who just asked politely...even if they were asking on behalf of their mother.
