You live in the SF Bay Area. There is a significant Indian population here, yet there is not a single large Indian grocery store. Chinese, Korean, Japanese, Vietnamese all have them but not Indians. Only have tiny stores barely bigger than convenience stores.
You haven't been to Sunnyvale. They have that India Cash and Carry and some other stores. Heck just recently the local Korean HanKook market closed down and an Indian store opened in its place.
