Bistro chops rind with energy (5)
I believe the answer is:
diner
'bistro' is the definition.
(thesaurus)
'chops rind with energy' is the wordplay.
'chops' indicates an anagram (I've seen 'chopped' mean this (letters chopped or smashed up)).
'with' indicates putting letters inside.
'energy' becomes 'e' (physics symbol as in E=mc2).
'rind' is an anagram of 'dinr'.
'dinr' placed around 'e' is 'DINER'.
(Other definitions for diner that I've seen before include "one taking several courses" , "Buffet car" , "American cafe" , "American restaurant" , "Eater" .)
