Bar selling other drinks (5)
I believe the answer is:
ingot
'bar' is the definition.
(block of metal, eg a bar of gold)
'selling other drinks' is the wordplay.
'drinks' indicates the answer is hidden within the clue (words in the clue have absorbed the answer).
'INGOT' is hidden within 'selling other'.
(Other definitions for ingot that I've seen before include "Mass of metal, especially gold or silver" , "expensive block" , "this must be cast" , "Bar of bullion, for example" , "Seize quickly; steal" .)
