Pub diet? (5)

I believe the answer is:

local

This clue is a double definition.

'pub' is the first definition.
(one's local pub)

'diet?' is the second definition.
(lo-cal is short for 'low calories')

(Other definitions for local that I've seen before include "nearest boozer!" , "(Pub) of the district" , "Village inn" , "Restricted number" , "where the neighbours drink?" .)

I've seen this clue in The Independent and The Guardian.
