Don't you think pub has appeal? (5)
I believe the answer is:
'don't you think' is the definition.
'pub has appeal?' is the wordplay.
'pub' becomes 'inn' (I've seen this before).
'has' says to put letters next to each other.
'appeal?' becomes 'it'.
(Other definitions for innit that I've seen before include "Isn't it (sl.)" , "word of emphasis" , "Common question" , "do you agree?" , "that produces stress for some" .)
