Old Los Angeles Zoo (long since closed)

I enjoyed poking around this rather desolate building. Any idea what it once was?

@sooty mangabey I was with Mario (@mstickmanp ) and he had a cool map of the old Los Angeles Zoo and so he pointed out the hoofstock area, carnivore zone, elephant habitat, old Director's House (at the top of the hill looking down on everything) and this building in the photo might have been the Veterinary structure but Mario would know for sure. It was exciting to have a map to refer to while puttering around the grounds.

@sooty mangabey From what Mike Dee told me this was the zoo kitchen and food storage area.
