Bloke keen, some say, to establish wine shop (6)
I believe the answer is:
bodega
'wine shop' is the definition.
(I've seen this before)
'bloke keen some' is the wordplay.
'bloke' becomes 'bod' (I've seen this in other clues).
'keen' becomes 'eg' (I can't explain this - if you can you should give a lot more credence to this answer).
'some' becomes 'a'.
'bod'+'eg'+'a'='BODEGA'
'say to establish' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bodega that I've seen before include "Span. wine shop" , "booze shop" , "Shop or cellar in Spain for selling wine" , "concern for alcohol" , "Small Hispanic wine-shop" .)
