Start at the top (temporary installations) and work your way down. Try not to miss a room, painting, photo, item, floor - including the basement!
Highlights - the cloud room, the big lazy furniture on some of the floors, and the B&W photo booth. The food is pretty good too. Bring friends and make an afternoon of it.
Love it. It's not really a young kid friendly place, unless you stick to some of the lower floors and basement, but it's definitely fun for older kids and adults!
