I work not too far away and would be happy to catch up - work allowing..
For food, I can recommend the Boot & Flogger - saved a rapidly deterioraiting experience at some bar on the corner of London Bridge Road and Southwark Steet:

For drinking, I used to go to the Wheatsheaf (I think now called the Sheaf). The food was bar food and not bad, too... Haven't been in a while though.
The Market Porter is a reasonably good drinking pub (straddles Borough Market), but my favourite drinking pub around there was the White Horse - which is about a 10 minute walk,... But I haven't been drinking that way since abut 2014 (Had dinner at the boot and flogger about 6 months ago).
Fair warning - I prefer basis drinking establishments with a bit of character - not posh, pretentious places.
