That's because the capital city's hustle and bustle was brilliantly recreated inside a major convention centre with a stunning makeover for a massive international recruitment event staged by the social networking giant Linkedin.
Area 51 turned a huge events room into a microcosm of the UK capital city complete with streets and gardens, London buses and black cabs, terraced mews buildings, a traditional London pub and even obligatory road works.
Add to that a collection of walkabout characters including bobbies on the beat, construction workers, a Cockney pub landlord and staff plus even a couple of jobsworth traffic wardens and London street-life materialized in front of the eyes of delegates who jetted in from four corners of the globe for the Linkedin event, Talent Connect, Europe's largest ever corporate recruiting event.
The eye-catching collection of décor, scenery, props and performers was intelligently embellished by stunning functionality. Area 51's design team ensured delegates' needs were met by discreetly siting power points so laptops, tablets and smart phones could be plugged in, ensuring the space was fully covered by wi-fi while the space was made to work for everyone on all kinds of levels.
Not least in terms of ensuring everyone was fed and watered. As well as the London boozer being open for business, there were coffee bars, catering outlets and even a barbecue at night.
A line of mews "houses" served as individual meeting rooms that could be pre-booked by delegates.
It was a huge project which started seven months earlier in the embryonic design stage but the actual installation had to be completed in just 48 hours from scratch with a space measuring 65 metres by 30 metres needing to be fully revamped before the two-day event began - a 60-strong crew from Area 51 ensured the scheme was successfully carried out leading to a stunning reception from people attending.
At the end of the two day conference Area 51 staged a party night function utilising a DJ and other performers.
