Frightfully posh eat here (3,4)
I believe the answer is:
tea shop
'here' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'frightfully posh eat' is the wordplay.
'frightfully' is an anagram indicator (I've seen this in other clues).
'posh'+'eat'='posheat'
'posheat' is an anagram of 'TEA-SHOP'.
Can you help me to learn more?
(Other definitions for tea shop that I've seen before include "refreshing facility" , "Cafe (paradoxically?)" , "Small cafe" , "Restaurant serving light meals" , "Refreshments provider" .)
