Avoid drink in street (5)
I believe the answer is:
skirt
'avoid' is the definition.
(skirt can mean to go around or avoid)
'drink in street' is the wordplay.
'drink' becomes 'kir' (I've seen this before).
'in' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'kir' inserted inside 'st' is 'SKIRT'.
(Other definitions for skirt that I've seen before include "Leave the pack" , "Try to avoid (a problem)" , "Ladies' garment" , "Circumvent" , "Garment below the waist" .)
