Visit the Hunterian Museum for the freakiest stuff: pickled organs, skeletons of giants, and a cabinet of curiosities that will make you question your life choices. It’s not for the faint of stomach. But you’ll never forget it, which is the whole point.
Finally, remember this: the British queue. They love a queue. If you see a line, get in it. You don’t know what it’s for, but you will wait. It could be a new Harry Potter exhibit. Or it could be a bus stop. Either way, you will stand in silent, polite solidarity with strangers, and that, my friend, is the true London experience.
