Bar’s got up pretentiously as this? (9)
I believe the answer is:
gastropub
'this?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'bar's got up pretentiously' is the wordplay.
'bar's got up' can be anagrammed to 'GASTROPUB'.
However, I'm not sure how the anagram is indicated.
'as' is the link.
Can you help me to learn more?
(Other definitions for gastropub that I've seen before include "Local converted into trendy restaurant" , "Eaterie" , "Bogus trap (anag) -- somewhere good to eat and drink?" , "Bar serving high-quality food" , "Local with good food" .)
