I'm a student due to start my first job in the City next month (I'm
terrified, I've only ever been to London 5 times!!).

Can anyone give me any advice on how to get around London late(ish) at
night? From, say, Bank station to Hanger Lane. How safe is the tube at
about 11pm? Does anyone local know how much a cab to the Hanger Lane
area from the City would cost?

Any advice really would be much appreciated,

Adam
