I remember the Chelsea cruise George. I think the tea hut is still there but not sure if it still sells tea these days or designer lattes for the residents in the fancy new flats located all along the street. I did on a couple of occasions participate in the high speed ride from Chelsea Bridge to the Heston Services on the M4 which was quite a 'thing' to do back in the day and before the blight of speed and average speed cameras.
When I worked above the huge Victoria Coach Station I used to do a 5 mile run during my lunch hour and run over the bridge, past the tea hut, around Battersea Park and back, happy days😁.
