Trendy new pub (3)
I believe the answer is:
inn
'pub' is the definition.
(thesaurus)
'trendy new' is the wordplay.
'trendy' becomes 'in'.
'new' becomes 'n'.
'in'+'n'='INN'
(Other definitions for inn that I've seen before include "place to stay" , "Gray's, Lincoln's" , "Possibly Jamaica" , "English country pub" , "Hotel or public house" .)
