Since I live in SF and am fond of German baked goods, I was delighted to discover that Esther's German Bakery now has a stand in the Crocker Galleria Farmers' Market. The market is on Thursdays from 11-3 (not sure how late in the year it will run). Esther's is also hoping to open a retail outlet in Crocker Galleria, but nothing is for sure yet.
I recently tried an abundance of their baked goods and nearly everything was very good. The Broetchen were as close to the real thing as I have found around here.
