The Flying Scotsman; Caledonian Road, King's Cross, London
No. Don't. Not even to 'see just how bad it can be'. Really. Avoid at all cost. Not even if you're paid to go there. The best thing that could happen to it would involve a gallon of flammable liquid and a match. There is no helping this saloon, even if there's any architectural merit anywhere within its walls. Run from this place.
