Eccentric cheered men and met for drink (5,2,6)
I believe the answer is:
creme de menthe
'drink' is the definition.
(creme de menthe is a kind of drink)
'eccentric cheered men and met' is the wordplay.
'eccentric' indicates anagramming the letters.
'and' is a charade indicator (letters next to each other).
'cheered'+'men'='cheeredmen'
'cheeredmen' put after 'met' is 'metcheeredmen'.
'metcheeredmen' with letters rearranged gives 'CREME DE MENTHE'.
'for' is the link.
(Other definitions for creme de menthe that I've seen before include "spirit" , "Green liquid" , "Peppermint liqueur" , "Green-coloured liqueur" , "Sweet green or white liqueur" .)
