With no place to go, a gin looks awfully inviting (6)
I believe the answer is:
asking
'inviting' is the definition.
(I've seen this in another clue)
'with no place to go a gin looks awfully' is the wordplay.
'with no' suggests deleting specific letters.
'place to go' becomes 'loo' ('go' can mean 'urinate').
'awfully' indicates anagramming the letters.
'a'+'gin'+'looks'='aginlooks'
'aginlooks' with 'loo' taken away is 'aginks'.
'aginks' with letters rearranged gives 'ASKING'.
(Other definitions for asking that I've seen before include "Making request" , "Making enquiries" , "being inquisitive" , "Proposing" , "For the ___; freely available" .)
