Parisian is seen about freight delivering delicacy for him? (8)
I believe the answer is:
escargot
But I can't explain it at all! Could you help me understand?
(Other definitions for escargot that I've seen before include "French food" , "French delicacy" , "Hardly fast food" , "Got scare from edible French snail" , "mollusc, from Paris" .)
