My friend and I went on a low budget tour of SF and we found this place at Golden Gate Park. To our dismay, it costs money to enter, but we paid the price and were thoroughly pleased. The garden is not all that big, so do not imagine anything like the Huntington Garden in Pasadena. It is small and cozy and very peaceful. You can walk around the enter place in ten minutes. I recommend doing a few rounds and walking backwards and taking various paths to get to the same place because the experience every time is VERY different. I especially like this one bridge that is very difficult to cross, but very fun too. The stairs are nice and everything from the rocks to the plants are pleasing to the eye. I have not tried the tea at this place, so I am in no position to talk about that here.
