Dash back to eat at European business venue (7,6)
I believe the answer is:
trading estate
'business venue' is the definition.
The definition suggests a singular noun which matches the answer.
'dash back to eat at european' is the wordplay.
I cannot really understand how this works, but
an anagram of 'eat' is 'ate' which is present in the answer.
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is found within the answer.
'european' could be 'e' (abbreviation e.g. EU) and 'e' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trading estate that I've seen before include "Area with factories" , "industrial park" , "where the industrial firms are concentrated?" , "Industrial and commercial area" , "Commercial zone" .)
