Better than expected! The structure itself is novel, and you get to travel from sphere to sphere using stairs and escalators that move through the tubes linking the spheres. They also had some fun exhibits of propoganda and advertising from the 50’s, and several rooms of really entertaining LED light shows. The light shows qualified as works of art and made good use of the strangely-shaped interior space. There was a restaurant in the top sphere that required reservations. We wished we had made them, just for the novelty of being in that space.
