Rich,
I see Rebecca Wheeler, who I think may own WS, is leading the shopping trip on September 12. See details

However, I would suggest grabbing a copy of Lonely Planet's World Food Guide for Vietnam. After reading this short guide, walking through an Asian market was a whole new experience.
FYI, I always thought WS was a bit on the pricey side for some of their fairly standard classes....if someone has experience that says it is worth every penny, please advise.
FYI2, I have had good luck with the Francis Parker School classes (more than just the food ones, also) and to a lesser extent with Latin School....these evening courses help fund scholarships.
