Place to chow down on tuck (5)
I believe the answer is:
pleat
'tuck' is the definition.
(I've seen this before)
'place to chow down on' is the wordplay.
'place' becomes 'pl' (abbreviation used in postal addresses).
'to chow down' becomes 'eat' (I've seen this in another clue).
'on' means one lot of letters go next to another.
'pl'+'eat'='PLEAT'
(Other definitions for pleat that I've seen before include "Gather" , "Fold in a skirt" , "Fold in material" , "Fold formed in fabric" , "Crease" .)
