Banking, law, consultancy, medicine. With law though (I don't know about the other fields) you need to be at a big London or US firm to really bring in the money, and, except for Magic Circle or US firms, be a partner generally. With some of those firms, you can start as a newly qualified solicitor on over £100k. You'd have to sell your soul though, and would be regularly working through the night, cancelling plans and sometimes even holidays.
I remember being called by a corporate law colleague, probably 4/5 years PQE, from a very close family member's funeral, because we were in the middle of a deal that was closing that day. I wouldn't wish that on anyone, although I imagine he is doing very well financially now!
I took a sideways step a long time ago, as I couldn't take the pressure, but if I had been capable of carrying on and made partner at the firm I started at, I would be raking it in now. Horses for courses, I guess.
