These were all the rage a few years back, but the enthusiasm seems to have receeded. Best I've had were the ones served at Santa Monica Place mall, but the stall has long since been converted into a Mongolian BBQ outfit (providing ingredients that have been no where near Mongolia since the breakup of Pangea 180 million years ago).
Turkey must be freshly roasted, and gravy, peppers and other garnishments plentiful. French-type roll preferred by not mandatory. Any leads out there?
PS the one at Farmer's Market don't cut it.
