Turkey with plain dressing served around northern resort (9)
I believe the answer is:
llandudno
'resort' is the definition.
(I've seen this before)
'turkey with plain dressing served around northern' is the wordplay.
I cannot really understand how this works, but
'turkey' could be 'dud' (synonyms) and 'dud' is found in the answer.
'around' could be 'o' (a round letter) and 'o' is located in the answer.
'northern' could be 'n' (abbreviation e.g. N. Ireland) and 'n' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for llandudno that I've seen before include "Welsh seaside town" , "Welsh seaside resort" , "North Wales seaside resort" , "holiday destination" , "Welsh coastal resort" .)
