NGPC
Wander among restored (mostly) vintage cars in a comfortable, well-lighted environment. A $15 admission fee, and you can purchase your ticket online at savoymuseum.org.
Please note: you are not allowed to carry large bags past the lobby. There are lockers you can use for free to stash the bag. A small bag with one lens is about the limit in addition to your camera.
There is a cafe off the lobby if you need food or drink.
