'unsettle' is the definition.

'dance venue ready to rake in millions' is the wordplay.
'dance venue' becomes 'disco' (I've seen this before).
'ready' becomes 'fit' (I've seen this in another clue).
'to' means one lot of letters go next to another (I've seen this in other clues).
'rake in millions' becomes 'm' (I can't justify this - if you can you should give a lot more credence to this answer).
'fit' after 'm' is 'mfit'.
'disco'+'mfit'='DISCOMFIT'
