Hoping to draw wisdom from the resident West Burbs experts. While I know of two markets near the Downers Grove / Westmont area, I was asked to suggest a Mexican Market that is closer to Naperville as a potential source for whole dried chipotle chiles.
Yes, yes, I know -- the city is a gold mine where Mexican Mercados (fruterias, carnecerias, etc.) are concerned (which is part of why you'll see us at the June 1 event...).
Even so, I'd love to hear about additional options in suburbia (for my own purposes, when I can't run into the city)...
