Beers had in local? Especially good! (4)
I believe the answer is:
ales
'beers' is the definition.
(I've seen this before)
'in local? especially good' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ALES' can be found hidden inside 'local especially good'.
'had' acts as a link.
(Other definitions for ales that I've seen before include "Types of beer" , "A sale of beers" , "Alcoholic drinks" , "What might be delivered by pumps" .)
