Writers taking in street restaurants (7)
I believe the answer is:
bistros
'restaurants' is the definition.
(bistro is a kind of restaurant)
'writers taking in street' is the wordplay.
'writers' becomes 'biros' (I can't explain this - if you can you should give a lot more credence to this answer).
'taking in' indicates putting letters inside.
'street' becomes 'st' (abbreviation).
'biros' placed around 'st' is 'BISTROS'.
Can you help me to learn more?
(Other definitions for bistros that I've seen before include "Informal restaurants" , "places to eat..." , "Dread" , "Bars" , "Small restaurants" .)
