Will be staying in Richmond, won't have access to a car, but hoping to bring back stuff that won't be confiscated at the airport. Please only recs for stuff I wouldn't be able to order online or buy at home. Thanks! Also, I'm more a savory snack type person than sweets, although I do love chocolate.
For instance, before the chinese "olive oil" (cantonese: gai lam yao)condiment -- for noodles, rice dishes, etc could be purchased locally here in SF, a friend brought it back for me from a trip.
