Where's the best place for kids to see animals?  The zoo, of course! 
Not only are many zoos the home to exotic animals, but they are also
bastions of conservation and rescue.  Watching kids and animals interact
can be quite fun, as shown in this video uploaded by Kittens Guide on December 8, 2015.  It is a bit long (around 13 minutes), but quite fun!

I've been to the Atlanta Zoo (quite impressive) and been on the other side of the glass from an alpha male gorilla.  I can't say I was not unnerved.  But kids... they have that innocent curiosity that overcomes fear...
