I almost never fly to any of BA's destinations that go from LHR T3, but will have a few hours to kill there on Monday. Which lounges are worth a look if I were to do some lounge-hopping? I have BA Gold and Priority Pass.

I'd previously quite liked the CX lounge (and its noodle bar) - is the AA lounge worth a try? And are any of the PP offerings any cop?

Thanks in advance for your opinions!
