More than one bar is to be found round centre of Pinner (4)
I believe the answer is:
inns
'more than one bar' is the definition.
(I've seen this before)
'is to be found round centre of pinner' is the wordplay.
'to be found round' means one lot of letters goes inside another.
'centre of' indicates the central letters.
The centre of 'pinner' is 'nn'.
'is' placed around 'nn' is 'INNS'.
(Other definitions for inns that I've seen before include "Drinking places (frequented by barristers?)" , "Roadhouses or courthouses" , "Places of rest and sustenance for travellers" , "King's ..., for the legal eagles" , "Drink here and learn about the King's law" .)
