Street cooker — that’s odd! (7)
I believe the answer is:
strange
'odd' is the definition.
(thesaurus)
'street cooker' is the wordplay.
'street' becomes 'st'.
'cooker' becomes 'range' (I've seen this in other clues).
'st'+'range'='STRANGE'
'that's' acts as a link.
(Other definitions for strange that I've seen before include "Different" , "Foreign" , "Abnormal" , "Surreal" , "Out of the ordinary" .)
