Without a taxi back, gets something to eat (5)
I believe the answer is:
bacon
'something to eat' is the definition.
(bacon is a kind of food)
'without a taxi back' is the wordplay.
'without' becomes 'no'.
'a taxi' becomes 'cab' ('cab' can be a synonym of 'taxi').
'back' says the letters should be written backwards.
'no'+'cab'='nocab'
'nocab' backwards is 'BACON'.
'gets' acts as a link.
(Other definitions for bacon that I've seen before include "Man killed by chicken, some say" , "English philosopher, d.1626 - Irish painter, d. 1992" , "What the breadwinner brings home?" , "early scientist" , "Meat (brought home by a breadwinner?)" .)
