Working as a Physiotherapist in London

Hi, Im currently working on the south coast in a large acute trust. I'm thinking about moving to London to work and just wondered if anyone could give me an overview of what it is like to work in one of the big London trusts, e.g. teaching, progression etc? And if anyone could recommend a specific place of work. I've got an Interview for Imperial Healthcare NHS Trust coming up and Im just trying to weight up the pro's and cons at the moment, and if the teaching opportunities etc will be better.

Many Thanks:D:)
