We went to this teeny tiny little crazy zoo- Villa Fantasia in Zapopan. In general M and I are of the mindset that zoos are pretty sad. This type in particular, with small cages, random animals and being able to get shockingly close, was rough. The kids, however, loved it.
P.S. If you are in the Guadalajara or Zapopan area, we do recommend visiting the Guadalajara Zoo which has an amazing Safari and Aquarium as well.
