I need advice from someone who lives in London?

[wesleysgirl]

I'm working on a short story for a charity fundraiser. The story is m/m bdsm set in London and a bit of it includes enough travel on the Tube that I'd like someone who is quite familiar with London to give it a quick read and tell me where I've got things horribly wrong. The story's not done yet, but when it is, would anyone be willing?
