I've found recently a second variant of pronunciation of 'cafe' word: http://www.oxforddictionaries.com/definition/english/cafe.
The usual one is /ˈkafeɪ/ ˈkæ-'fay
But the OD link gives this too: /ˈkafi/ ˈkæ-fee
I have heard this second pronunciation before on BBC. I'm eager to know if it's formal/informal version? Who and when say that?
