Yeah. Every year I have been down London, we always had a ride on a double decka. Ironicaly, the bus services in my Grandfathers area of outer London are operated by double decka's and thats what we used to get to the tube stations. Route 282 which runs to Northolt & Eastcoate tube stations was operated by single deckas. While in London this and last year, me and dad rode on the iconic Routemaster. There's not many about now and the last few in service operate a designated heratige route.
