Art deco building right by the eastern edge of Soho - tourists were entertained there (9)
I believe the answer is:
trocadero
'the eastern edge of soho tourists were entertained there' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'art deco building right' is the wordplay.
'building' indicates an anagram.
'right' becomes 'ro' (I can't explain this - if you can you should give a lot more credence to this answer).
'art'+'deco'='artdeco'
'artdeco' is an anagram of 'trocade'.
'trocade'+'ro'='TROCADERO'
'by' is the link.
Can you help me to learn more?
(Other definitions for trocadero that I've seen before include "Battle scene" , "London restaurant opened by J. Lyons & Co in 1896, closed 1965" , "Area across Seine from the Eiffel Tower, decorator (anag.)" .)
