On one hand I'm sorry for doing the Londoncentric thread; on the other, I'm not, because I live there
Anyway, as we all know the best and coolest thing to be able to do is be the person who knows of a bar/pub that is still open when all others are closing. On one hand this encourages alcoholism and the dangers associated with alcohol consumption; on the other hand something something. Let us share this knowledge and impress our horrible friends.
Aldgate: The Castle
Pretty disgusting dive pub where the bouncer charges you an indiscriminate amount to get in depending on the look of you. The music is bad.
Pretty disgusting, but really good. The barman may be mental. They serve dark budvar.
Absolutely disgusting. Pretty metal.
Kennington: The Doghouse.
Lovely late-opening pub. Serves that cloudy cider that make you go blind.
