Upstanding winner of Nobel Peace Prize, I'm a little cooler (7)
I believe the answer is:
minibar
'a little cooler' is the definition.
(something which keeps drinks cool)
'upstanding winner of nobel peace prize i'm' is the wordplay.
'upstanding' shows that the letters should be reversed in order.
'winner of nobel peace prize' becomes 'Rabin' (Yitzhak Rabin, 1994 Nobel Peace Prize winner).
'rabin'+'im'='rabinim'
'rabinim' backwards is 'MINIBAR'.
(Other definitions for minibar that I've seen before include "Hotel bedroom fridge" , "Hotel room chiller?" , "Source of hotel room drinks" , "cooler for hotel guest?" , "Hotel room fridge" .)
