Business bureau Tory pal ruined (6,7)

I believe the answer is:

beauty parlour

I'm a little stuck... Click here to teach me more about this clue!

'business' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'bureau tory pal ruined' is the wordplay.
'ruined' indicates an anagram.
'bureau'+'tory'+'pal'='bureautorypal'
'bureautorypal' with letters rearranged gives 'BEAUTY-PARLOUR'.

Can you help me to learn more?

(Other definitions for beauty parlour that I've seen before include "Grooming salon" , "Establishment for prettification" .)
