Cool food generating some publicity? (7)
I believe the answer is:
fanfare
'some publicity?' is the definition.
(I've seen this in another clue)
'cool food' is the wordplay.
'cool' becomes 'fan' (I've seen this in another clue).
'food' becomes 'fare' (fare is a kind of food).
'fan'+'fare'='FANFARE'
'generating' is the link.
(Other definitions for fanfare that I've seen before include "Short ceremonial tune for trumpets" , "Enthusiastic display" , "Musical flourish" , "Flourish of trumpets" , "Short piece of music played on brass instruments (for the Common Man?)" .)
