The last one was really tough and only one person got it right Guess Where Tube 7 (see the comment I left just now) - so this time I'm being easier on you.
Today's "Guess where Tube" features one of those "Dangerousdoors" on the Tube.
I love the slightly Steampunk feel this one has. Again I'll say it's one where if you really know where it is, you'll get it straight away. If you don't it will be harder. So really try not to look at the comments in front of you before making your guess.
Once again, there's no prizes for getting it, just the satisfaction of knowing you were right.
