Where is the best place to get really good tea in the Bay Area?

I think this question might be helpful. It is also about finding tea in the San Francisco bay area.

Japanese Tea Garden in Golden Gate Park.

The Republic of Tea is a merchant that imports fine teas from all over the globe. I have an Aunt who works for them and from my Christmas gifts from her I know they have really awesome loose leaf teas. They’re a chain but are based in Marin. I do believe they have several retail outlets in the city though.
