I have been going to the San Francisco Zoo for years. It has been improving a lot lately. They have a new African section, where you can see giraffes and zebras when you are coming into the zoo. They recently added a parking lot which is convenient. The food is getting better again too. They still have the upgrades they made a few years ago, and now they have added an "Asian food" section. They have a playground for the kids, a place to have a(n expensive) birthday party, and kettle korn! They also have a nice lemur exhibit and just opened a new bird exhibit. It is also very convenient to the beach if you want to do that as well.
