Particular, distinctive (7)
I believe the answer is:
special
I believe this is a double definition.
'particular' is the first definition.
(I know that particular can be written as special)
'distinctive' is the second definition.
(distinctive can mean special or different)
(Other definitions for special that I've seen before include "An addition to the standard menu" , "Different from usual" , "Rare, valuable" , "Dish not on regular menu" , "Dish not on the normal menu" .)
