Notreally gender neutral as theystill say mens and womens on them but yay for the sign. They have them at Jagged Little Pill and Frozen too. As someone who is non binary I appreciate not getting questioned no matter which bathroom i use."
Regarding the fact that they still have the men and women signs: Strangely enough, this is part of an outdated law on the books for theaters in New York. It was enacted long ago, because many theaters had their women's restrooms located in a place where one would have to exit the theater in order to use it. So even in the cold, there would be a line outside the building of women b/c that restroom had an outside entrance. Eventually a law was put in place dictating that theaters must have indoor space for both men and women's room so as to treat everyone equally.
The theater I worked for discovered this during a renovation. The original reno plan included one large gender neutral restroom with many individual floor to ceiling stalls. However we found out that this old law required us to have a men and women restroom. So we could only have a specific gender neutral one if we were to build a third restroom, which there was no room for. The law would probably be pretty easy to fight and be changed (it was great for it's time, but no one has bothered to change it as times have changed), but many theater organizations dont have the funds or times to take on that legal battle. So my theater, like many others, still have men and women restrooms, but they are accompanied by signs stating that they support patrons using whichever space aligns with their gender identity.
