I have been looking for really good German Stollen for the Holidays. I usually just come across the industrially produced kind, e.g. made by Bahlsen. Even the one they sell at Trader Joe's tastes very bad.

Any ideas for an alternative?

I second Sterntaler Bakery for a really good German bakery for breads, pretzels and cakes (especially their Stollen - yumm). I think they are based in San Carlos.
