Oddly slow Friday in the city (5)
I believe the answer is:
sofia
'the city' is the definition.
(Sofia is an example)
'oddly slow friday' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'slow'+'friday'='slowfriday'
The alternating letters of 'slowfriday' are 'SOFIA'.
'in' is the link.
(Other definitions for sofia that I've seen before include "seat of government" , "Bulgarian city" , "capital place" , "Capital of Bulgaria" , "Foreign city" .)
