Yes, it’s raining. But walking the South Bank in a light drizzle is magic. The London Eye spins slow and ghostly. The street musicians play under awnings. No one cares—everyone is just living in a movie scene.
Pop into the National Theatre. Even if you don’t see a play, the concrete foyer is free, warm, and has massive windows. Watch the rain hit the Thames. It’s free theater. You can even nap on the sofas for an hour. No one judges.
