We saw a very good show on the architecture and design of City Center. The docents were very helpful. One offered to get me a pencil and paper to take notes. The audio guide could be more informative, but it was fairly decent. The gallery is a good deal if you are a Nevada resident. They offer a special locals night on Wednesdays for $8 per person. It is a bit small, but consider that a plus if you wish to get in depth with the exhibits.
