A way-out drink? (5)

I believe the answer is:

stout

'drink?' is the definition.
(stout is a kind of drink)

'a way-out' is the wordplay.
'a way' becomes 'st' (abbreviation for street).
'st'+'out'='STOUT'

(Other definitions for stout that I've seen before include "Bulky" , "Portly or stalwart" , "Round" , "Corpulent" , "Portly - porter" .)

I've seen this clue in the Evening Standard.
