Snuffy, if you are interested in buying some of these products, in my humble opinion the best of these stores is found on Benito Gonzalez, about halfway down the block heading East, on the south side, just after a restaurant.. I think in fact it is the same store where Chiri took her pix. They have the best selection and the store is large. the store across the street on the north side has many of the same things, but it is more cramped and doesnt seem to offer as wide a selection. There are furniture stores too, on the Duarte, and video stores, and chinese medicine, too.
If anyone knows of a good chinese doctor, let me know. Always good to have a skilled acupuncturist on hand. There is a place on Lea de Castro called Neijing Garden, or some such thing, which I think practices japanese style acupuncture, but I havent enquired yet.
