Give opinion on drink served in place full of tourists? (7)
I believe the answer is:
airport
'place full of tourists?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'give opinion on drink' is the wordplay.
'give opinion on' becomes 'air' (I am not sure about this - if you are sure you should believe this answer much more).
'drink' becomes 'port' (port is a kind of drink).
'air'+'port'='AIRPORT'
'served in' acts as a link.
Can you help me to learn more?
(Other definitions for airport that I've seen before include "See 18" , "where flight begins or ends" , "Liverpool's John Lennon, for example" , "Eg, Heathrow" , "Heathrow, for example" .)
