Fix pub providing service found on the high street (4,3)
I believe the answer is:
nail bar
'service found on the high street' is the definition.
I know nothing about this answer so I can't tell whether this works.
'fix pub' is the wordplay.
'fix' becomes 'nail' (I've seen this before).
'pub' becomes 'bar' (both are drinking establishments).
'nail'+'bar'='NAIL BAR'
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for nail bar that I've seen before include "Manicure salon" , "Manicurist's establishment" , "Type of beauty parlour" .)
