210 Brent Cross to Finsbury Park. A famous London bus route that links Hampstead Heath and Highgate village. Sharp intake of breath as the driver positions the bus carefully to squeeze through the narrow gap next to the Spaniards Inn!  Amazingly this route has recently been converted to double-deckers. The last time double-deckers ran on this route was probably in the 1920's. Frequent service.
