Shabby cinema or theatre (7)
I believe the answer is:
fleapit
I believe this is a double definition.
'shabby cinema' is the first definition.
(I've seen this before)
'theatre' is the second definition.
(I know that fleapit is a type of cinema)
(Other definitions for fleapit that I've seen before include "Shabby old cinema" , "jumper" , "Run-down place for pictures" , "dive?" , "shabby public building" .)
