One’s found stunning spot — at city’s limits? (3,5)
I believe the answer is:
eye candy
'one's found stunning' is the definition.
(an attractive person)
'spot at city's limits?' is the wordplay.
'spot' becomes 'eye' (I have seen 'Symmetrical spot' mean 'eye' so perhaps 'spot' could also mean 'eye').
'at' says to put letters next to each other.
'city's limits?' becomes 'candy' (I can't explain this - if you can you should give a lot more credence to this answer).
'eye'+'candy'='EYE CANDY'
(Other definitions for eye candy that I've seen before include "Beautiful people" , "One's found stunning" , "visual feast" , "One who is visually pleasing" , "Visually attractive thing" .)
