Drink or meal done badly (8)
I believe the answer is:
lemonade
'drink' is the definition.
(lemonade is a kind of drink)
'meal done badly' is the wordplay.
'badly' is an anagram indicator (letters in the wrong order).
'meal'+'done'='mealdone'
'mealdone' is an anagram of 'LEMONADE'.
'or' acts as a link.
(Other definitions for lemonade that I've seen before include "it refreshes" , "Ale demon (anag)" , "Diluted fruit drink" , "Do enamel this strange drink" , "Leo named oddly for a soft drink" .)
