We loved this building, and took the audio tour inside and out. It also led to a garden on the 3rd floor, and onto a balcony, which showed you some of the surrounding buildings and the infrastructure behind all the metal panels which make up the exterior. The inside was very tasteful and the garden had many samples of plants, often labeled for info. Loved the shady garden, and the sculpture dedicated to Lillian Disney. Good views of nearby city streets below the garden, too.
One disappointment was that we were told that we'd be able to see the main concert hall, but that was retracted later on, since they then had someone practicing inside. It would've been nice for them to tell us to hurry and go in before it would be unavailable. We don't make it to the L.A. area very often. In case you don't remember, this building was used on the "Get Smart" movie, and we actually brought that along with us on our trip, and watched it again after seeing the concert hall: Lots of fun!
