Patty's place (3)
I believe the answer is:
bun
'patty's place' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bun that I've seen before include "Small cake or bread roll" , "Small cake; hair style" , "One from Chelsea" , "A small cake, sweet and round" , "Sweet roll and hairstyle" .)
