Outspoken Iberian's approval for cafe style (2,4)
I believe the answer is:
au lait
'cafe style' is the definition.
(cafe au lait is a type of coffee)
'outspoken iberian's approval' is the wordplay.
'outspoken' indicates a 'sounds like' (homophone) clue.
'iberian's approval' becomes 'ole' (Spanish word expressing approval).
'ole' sounds like 'AU LAIT'.
'for' is the link.
(Other definitions for au lait that I've seen before include "Like cafe drink" , "With milk (French)" , "White" , "Milk added" , "With milk in France, say coffee" .)
