Drink served with good meat that's checked (7)
I believe the answer is:
gingham
'checked' is the definition.
(I've seen this before)
'drink served with good meat' is the wordplay.
'drink' becomes 'gin' (gin is a kind of drink).
'served with' is a charade indicator (letters next to each other).
'good' becomes 'g' (abbreviation).
'meat' becomes 'ham' (ham is a kind of meat).
'gin'+'g'+'ham'='GINGHAM'
'that's' acts as a link.
(Other definitions for gingham that I've seen before include "Fabric in a plaid weave" , "Checked material" , "Cotton cloth woven with coloured checks" , "Striped or checked cotton cloth" , "Cotton cloth, maybe checked" .)
