Article on tax turning up in restaurant (7)
I believe the answer is:
taverna
'restaurant' is the definition.
(I've seen this before)
'article on tax turning up' is the wordplay.
'article' becomes 'an' (indefinite article).
'on' becomes 're' (regarding).
'tax' becomes 'VAT' (UK Value Added Tax).
'turning up' says the letters should be written backwards.
'an'+'re'+'vat'='anrevat'
'anrevat' backwards is 'TAVERNA'.
'in' is the link.
(Other definitions for taverna that I've seen before include "Small Greek restaurant with bar" , "pub" , "Greek inn" , "Greek bar/restaurant" , "Greek guesthouse" .)
