After reading about Chelsea apparently moving to Earls Court, I imagine that place to be exactly as it would be in the 90s- maybe the smash hits poll winners party being held there, or the daily mail ideal homes exhibition with guest appearance from Les Dennis.
The National Indoor Arena in Birmingham I reckon is still set up for Gladiators, but now only one Travelator works, the Atlaspheres are rusty and full of greggs wrappers and Lightning has got really bad visible roots.
Leicester Square- Dr Fox still operates out of the Capital FM Cafe, where if you're lucky you'll bump into her out of Republica or one of Hot n Juicy.
Farnborough- Still like the 80s. Giant dinosaurs made out of concrete which cut your hands if you tried to climb them. (Last time I checked it was still pretty 80s to be fair.)
