A spot to get smashed with grub? (9)
I believe the answer is:
gastropub
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for gastropub that I've seen before include "Bogus trap (anag) -- somewhere good to eat and drink?" , "Eatery" , "Local with good food" , "Place to eat" , "Bar serving high-quality food" .)
