Bar money in famous wedding location (7)
I believe the answer is:
cantina
'bar' is the definition.
(thesaurus)
'money in famous wedding location' is the wordplay.
'money' becomes 'tin' (I've seen this before).
'in' means one lot of letters goes inside another.
'famous wedding location' becomes 'cana' (reference to the biblical marriage at Cana).
'tin' going inside 'cana' is 'CANTINA'.
(Other definitions for cantina that I've seen before include "Spanish bar; Italian wine shop" , "rural Mexican bar" , "Spanish wine-shop" , "Concern for drinkers" , "Bar in Spain (or Star Wars)" .)
