A return visit on a quiet Tuesday night brought a different crowd. Possibly hedge fund managers and their… wives? First dates were happening, second and third, with couples dressed beyond anything I thought necessary for a Tuesday. Groups of pals who I imagine had come north from Guildford, or west from Basildon, were bedding in, sure not to spill gin on their leopard print. And selfies were happening in front of one of any number of elegant backdrops. As planes whizzed by and the sun melted into the horizon, memories were made 912ft up.
