A bit of a blow for those wanting refreshments (6)
I believe the answer is:
buffet
'a bit' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'a blow for those wanting refreshments' is the wordplay.
I cannot quite see how this works, but
'blow' could be 'buff' (I've seen this before) and 'buff' is found in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for buffet that I've seen before include "Batter - refreshment counter" , "Light refreshments - strike" , "Self-service meal; strike" , "Cold table" , "Variety of restaurant" .)
