Café noir starts to be served around resort of Agadir Bay (8)
I believe the answer is:
cardigan
'bay' is the definition.
(as in Cardigan Bay in Wales)
'cafe noir starts to be served around resort of agadir' is the wordplay.
'starts' indicates taking the first letters.
'to be served around' indicates putting letters inside.
'resort of' indicates an anagram.
The initial letters of 'cafe noir' is 'cn'.
'agadir' with letters rearranged gives 'ardiga'.
'cn' placed around 'ardiga' is 'CARDIGAN'.
(Other definitions for cardigan that I've seen before include "Man in charge" , "corgi" , "Lord and outer garment" , "clothes item" , "Knitted jacket" .)
