Good smell, like a genuine taverna (5)
I believe the answer is:
greek
'a genuine taverna' is the definition.
I can't tell whether this defines the answer.
'good smell' is the wordplay.
'good' becomes 'g' (abbreviation).
'smell' becomes 'reek' (reeking is a kind of smelling).
'g'+'reek'='GREEK'
'like' acts as a link.
Can you help me to learn more?
(Other definitions for greek that I've seen before include "(Unknown?) European language" , "Foreigner" , "National?" , "One from Salonika" , "Hellene" .)
