Coastal road — gosh, a suitable place! (8)
I believe the answer is:
corniche
'coastal road' is the definition.
(I've seen this before)
'gosh a suitable place' is the wordplay.
'gosh' becomes 'cor' (I've seen this in other clues).
'a suitable place' becomes 'niche' (I've seen this in another clue).
'cor'+'niche'='CORNICHE'
(Other definitions for corniche that I've seen before include "way along cliff edge" , "coast road by a cliff face" , "Cliff-face coastal road" , "Roller" , "My place" .)
