Visited mid week so small crowd and lots of room to walk and and enjoy the atrium. Fun because it's different - not your normal way to pass the time.
Friendly and knowledgable staff, clean facility, organized exhibits and centrally located right off the 101.
We had no idea we would be able to touch the manta rays, watch ants farm and check out some bees and fish on top of the butterfly experience. It's pretty much a one time visit for me - but I'm glad I knocked it off my list of things to so.
My favorite is the "butterfly body check" you need to undergo leaving the atrium. They search for stowaways. Lol
