I have been to many Zoos in the U.S. And Europe, San Diego is by far the best. One highlight was the polar bears where a brother and sister bear were wrestling in the pool providing 15 to 20 minutes of great entertainment. While this is the best zoo they need to upgrade there dining choices and food quality for the guests. Found choices and food Quality to be better ay the Safari Park which is owned by the zoo. But it is still a great place to see endangered species in fairly natural habitats.
