Just last week a new ice cream parlor opened on Castro St, right in the spot that used to be Ben & Jerry's. It's called Naia, and they have the most amazing stuff there. It's all made locally (Hercules, I believe), no preservatives, organic stuff, etc. etc. I love it because they have so many non-dairy choices. The Madagascar Vanilla Soy is amazing!
The stuff ain't cheap ($8 for a pint), but OMG is it yummy! I hope they do well enough to survive because I think I'm about to become addicted.
