Some people will argue that the Jubilee line extension at Westminster is deeper, but they’re wrong. They’re confusing “deep” with “dramatic.” Westminster station is famous for its massive concrete caverns and bright lights—like an underground shopping mall built by dwarves. It’s deep, sure, but Hampstead hugs the core of the Earth like a koala.

The Bakerloo line also has some deep stations, but they’re mostly old and creaky. The Bakerloo is like that grandparent who tells you they walked to school uphill both ways. Hampstead quietly says, “I walked to school six miles uphill—and then down 200 feet of stairs.”
