Getting the 42 will be by far the longest route to get there. Even on the timetable it's around an hour. By far the fastest is ED -> London Bridge -> Moorgate (Northern Line) -> Walk (5 minutes) Yes, you can get a tube from Moorgate but the platform changes and getting out at Liverpool St will put a surprising amount of time on that walk Personally (I've just done this in both directions), I get the bus from outside London Bridge Uber will, of course, be the easiest. FWIW The coach also goes from Liverpool Street (and Stratford). If you return outside of busy times (ie after 7pm) it can be faster back into town. And much cheaper
