The Grant Museum is a brilliant museum. When I was planning my trip to London I knew it was definitely one of the places I wanted to visit. It's not the biggest museum in the world. It doesn't have huge moving dinosaurs. It's not the best museum for toddlers (I know because I went with my baby brothers Sam and Harry). But if you are the tiniest bit interested in bones, or maybe just interested in cool or gross stuff you should definitely go.
Whoever picked the exhibits (or even just Robert Edmond Grant who set up the museum 170 years ago) seems to have a good idea of what's cool and what's not. Their jar of moles probably doesn't teach scientists anything but it's cool. (I bet more people go away talking about that than the tiger or quagga skeletons.) The micrarium (that's it at the top) is tiny but deeply cool. You could spend all day in there. Even the walrus baculum is cool, (but also slightly gross and weird to tell your mum about). Here's some of the other cool stuff:
