200 eastern parkway, brooklyn, new york
100% positive
Directions: in the lobby to the left when you enter the building.
Comments: no need to pay entry into museum. there are two handicap accessible single stall bathrooms that are also labeled as gender neutral. when i was last there (sept 2019) the museum also had a sign up in the restroom area saying people are allowed to use any bathroom that fits their gender identity.
