YEEEEEAH! @Rea - you should try the beef ribs at Duke's Brew and Cue right by Haggerston Station. Seriously, the best ribs I had in London. You need to book a table first. Also nearby is (or used to be) a bar called Draughts where you can play board games, it's pretty fun.
Another time you could go to Pitt Cue, also very good. You need to turn up and...queue. Near Oxford Circus. There's a blues bar nearby with live music too, I forget where or what it's called but it's tiny and it's always good! I'm sure if you asked around you could find it easy enough.
I have so many suggestions, but those two for sure you gotta try.
Thanks for the recommendations! Places noted and will be sure to check them out. :)
