Concerning meeting place producing income (7)
I believe the answer is:
revenue
'income' is the definition.
(I know that income can be written as Revenue)
'concerning meeting place' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'meeting place' becomes 'venue' (I've seen this before).
're'+'venue'='REVENUE'
'producing' acts as a link.
(Other definitions for revenue that I've seen before include "Money coming in" , "Government's income" , "made?" , "Gross business income" , "A country's income as from taxes" .)
