Wide open to an alfresco buffet? (9)
I believe the answer is:
outspread
'wide open' is the definition.
(thesaurus)
'an alfresco buffet?' is the wordplay.
'an alfresco' becomes 'out' (an alfresco meal is eaten outside).
'buffet?' becomes 'spread' (I can't explain this - if you can you should give a lot more credence to this answer).
'out'+'spread'='OUTSPREAD'
'to' is the link.
Can you help me to learn more?
(Other definitions for outspread that I've seen before include "Fully extended" , "Wide apart" , "Scattered" .)
