The zoo is huge consider its location (at SF). The place is very clean for a zoo and I am please with the condition of the restroom. I feel safe to let my son (3yrs old) walk around within my sight zone and no need to chase after him.

The membership fees are very reasonable compare to other parks. The only draw back is there is no drop off/pick up zone inside the parking lot. The zoo is totally worth for a visit for a family day.
