I’m vegan, so I’m working with a much more limited diet than the majority of the public, including members of this forum. In my experience, smaller zoos don’t tend to offer much in the way of entrees beyond the classic hot dogs, pizza, chicken tenders, etc, which bodes poorly for someone like me. The offerings at large zoos are usually at least a bit better — in fact, I actually had one of the best vegan burgers I’ve ever had at the San Diego Zoo Safari Park.
