Rambling up to cafe to get a hot drink (3,2,3)
I believe the answer is:
cup of tea
'a hot drink' is the definition.
(I've seen this before)
'rambling up to cafe to' is the wordplay.
'rambling' indicates anagramming the letters.
'up'+'cafe'+'to'='upcafeto'
'upcafeto' with letters rearranged gives 'CUP OF TEA'.
'get' is the link.
(Other definitions for cup of tea that I've seen before include "Face pout (anag.)" , "Our national panacea - personal field of interest" , "Hot drink" , "The English panacea" .)
