This clue could be a double definition.

'cafe' is the first definition.
(thesaurus)

'new dire restoration' is the second definition.

'has' is the link.

Can you help me to learn more?

(Other definitions for diner that I've seen before include "One eating a meal" , "(Person eating in) restaurant" , "Eater" , "Restaurant customer" , "American cafe" .)
