Article on wine container served up in restaurant (7)
I believe the answer is:
taverna
'restaurant' is the definition.
(I've seen this before)
'article on wine container served up' is the wordplay.
'article' becomes 'an' (indefinite article).
'on' becomes 're' ('on' can be mean 'with reference to').
'wine container' becomes 'vat'.
'served up' says the letters should be written backwards.
'an'+'re'+'vat'='anrevat'
'anrevat' written backwards gives 'TAVERNA'.
'in' acts as a link.
(Other definitions for taverna that I've seen before include "Greek guesthouse" , "Greek inn" , "Greek bar/restaurant" , "Small Greek restaurant with bar" , "pub" .)
