Queen Vic in south-east offers assistance (7)
I believe the answer is:
service
'assistance' is the definition.
(I know that service is a type of accommodation)
'queen vic in south-east' is the wordplay.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'in' is an insertion indicator.
'south east' becomes 'SE' (abbreviation).
'er'+'vic'='ervic'
'ervic' placed within 'se' is 'SERVICE'.
'offers' is the link.
(Other definitions for service that I've seen before include "Tennis opening shot" , "Act of assistance; ceremony" , "following 28 [SILVER]" , "See 15" , "start of action in court" .)
