Always empty eateries on top of Table Mountain (7)
I believe the answer is:
everest
'mountain' is the definition.
(Mount Everest)
'always empty eateries on top of table' is the wordplay.
'always' becomes 'ever' (synonyms).
'empty' suggests removing the centre.
'on top of' indicates taking the first letters.
'eateries' with its middle removed is 'es'.
The first letter of 'table' is 't'.
'ever'+'es'+'t'='EVEREST'
(Other definitions for everest that I've seen before include "Highest Himalayan mountain" , "High peak" , "Mountain on the Nepal-Tibet border" , "A mountain to climb" , "Himalayan mount" .)
