The response to my Moon Cake Festival below brought on this question.
What are the best Asian/Chinese centric farmers markets in the area?
If there are evening farmers markets such as those in South Pasadena, etc. this could be a shabby equivalent of Taiwan's famous night markets.
If any of these exist, I'd love to check them out.
I found the link below relating to LA county farmers markets. These are the markets which seem to have the best likelihood of Asian-centric veggies and foodstuffs.
Any input on any of these (or suggestions of your own?) I'm particularly interested in night markets (particularly with street food) but am open to all suggestions.
