Fix and save salon (4,3)
I believe the answer is:
nail bar
'salon' is the definition.
(nail salon)
'fix and save' is the wordplay.
'fix' becomes 'nail' (I've seen this before).
'and' means one lot of letters go next to another.
'save' becomes 'bar' (I've seen this before).
'nail'+'bar'='NAIL BAR'
(Other definitions for nail bar that I've seen before include "Type of beauty parlour" , "Manicurist's establishment" , "Manicure salon" .)
