Yeah, chicory coffee. I really like it.
The first experience I had with that was I think 1964 when I went through New Orleans and stopped for a few days. I recall the waitresses would ask if you wanted regular or chicory coffee. Good stuff. Also discovered Picayune cigarettes. Cough, cough, wow they were strong. Strangely enough, the next place I found them was at Disneyland. Probably not anymore, though.
There is a little Creole restaurant in San Luis Obispo, Bon Temp Cafe, that sells chicory coffee, so when I need a chicory fix, it's relatively easy to get.
