Here’s a shocking truth: London City is tiny. You can walk from Liverpool Street to St. Paul’s Cathedral in about 15 minutes. Actually, the whole Square Mile is only about a mile wide (shocking, I know). So if you’re not in a rush and your shoes aren’t made of pure vengeance, walk. You’ll discover hidden alleys named “Cloak Lane” or “Pudding Lane,” which was the start of the Great Fire of 1666. No, they don’t sell pudding there. It’s a scam.
Walking also lets you avoid the single most terrifying activity in London: cycling. Don’t cycle. The streets here are designed by people who hate cyclists, and the buses will honk at you with the fury of a thousand irritated geese. Stick to your feet. They’re free, and they don’t require a helmet.
