Hot drink in Eilat terrible (5)
I believe the answer is:
latte
'hot drink' is the definition.
(type of coffee)
'in eilat terrible' is the wordplay.
'in' indicates a hidden word.
'LATTE' can be found hidden inside 'eilat terrible'.
(Other definitions for latte that I've seen before include "Type of coffee" , "See 21" , "frothy cup" , "Frothy milky coffee" , "Espresso with frothy milk" .)
