As has often been mentioned, it's a tiny place. I walked by a few times trying to find a direct entrance only to realize it was essentially inside the Beat Coffehouse, a quick left towards the room in pink.
The room is smaller than a studio apartment if not also most of the spaces over at Container Park. (See review.) If you read all of the history and view the pictures slowly, it will probably take all of twenty minutes to complete the tour.
A minimum $5 donation is gently encouraged. There's also memorabilia available for purchase as well as the opportunity to become a supporting member.
If you're interested in or just curious about burlesque, it's worth a stop.
