I'm in a far-flung area of NYC but can't find a source (I want it for an exotic pesto dish). Not the supermarkets, not the farmer's market, not the local greengrocer. I find this kind of extraordinary. You can easily get escarole, Boston, romaine, iceberg, arugula, and the more exotic baby greens, but not chicory. Not even the Dean & Deluca on Broadway in NYC had it.
