DD has been around for decades, but its creep has increased as the years go by. When I lived in Connecticut, and earlier in Rhode Island, I watched it fill available corner lots and storefronts with alarming determination. There are still local shops that will brew you a cuppa joe, but I suspect by century's end DD will dominate the field even more than it does now, if corporate HQ has their way.
Common chicory in flower
The Crescent City coffee scene seems more varied. Community Coffee and PJ's are easy enough to find and there are a few Starbucks, but the little guys still have clout in their neighborhood niches. I've been to Cafe du Monde once as a tourist, but I haven't been back. I'm no coffee connoisseur and I'm content with pretty much anything that's hot. This may be why I haven't noticed the chicory that is supposed to be the hallmark ingredient of New Orleans coffee that separates it from all other blends.
Chicory coffee may be a myth used to lure tourists, another legend like voodoo that helps cement New Orleans' reputation as a unique place on the globe. I know it's an ingredient in the Cafe du Monde blend and I've seen it listed on the sides of cans in the supermarket. I just don't know how common it is. My unsophisticated palate may never know the difference. The issue bears further investigation.
With all its experiments over the years, I don't recall Dunkin' Donuts test marketing a cajun blend of coffee featuring chicory. Of course, Boston did recently acquire two Popeye's Chicken outlets so it may just be a matter of time before DD starts selling this combination of two natural diuretics in a brew.
