Drink served up, suitable for antelope (6)
I believe the answer is:
reebok
'antelope' is the definition.
(I've seen this before)
'drink served up suitable' is the wordplay.
'drink' becomes 'beer' (beer is a kind of drink**).
'served up' says the letters should be written backwards.
'suitable' becomes 'ok'.
'beer' in reverse letter order is 'reeb'.
'reeb'+'ok'='REEBOK'
'for' is the link.
(Other definitions for reebok that I've seen before include "African runner" , "South African antelope (E, not H)" , "South African animal" , "Antelope of southern Africa" .)
