Get nothing after gold in Floridian city (7)
I believe the answer is:
orlando
'floridian city' is the definition.
(I've seen this before)
'get nothing after gold' is the wordplay.
'get' becomes 'land' (landing is a kind of getting).
'nothing' becomes 'O' (O resembles 0).
'after' says to put letters next to each other.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'land'+'o'='lando'
'lando' put after 'or' is 'ORLANDO'.
'in' acts as a link.
(Other definitions for orlando that I've seen before include "Florida resort -- Virginia Woolf novel" , "The city in America" , "Bloom for one" , "Bloom in film" , "American themepark location" .)
