The one by southbank is called Arcadia. Think the same guy is doing work for them. here's a press spiel:
There's a new London space set to take the underground music scene by storm this autumn, and it's called... Arcadia. Nestled away beneath the bricked, arched walls of five railway arches tucked behind the South Bank of London's river Thames. Where the space was formerly a very low key, friendly place, the re- launched Arcadia will be a more all encompassing venue with weekly events which cater to all types of people, and to all music tastes.
From the new team of promotions you can expect on rotation include so far 'Riot, Eight:FX, Lets Go Crazy, La Dolce Vita and Fusion' – all of whom are keen to take this previously unknown venue to the next level. The club launches fully on October 1st with charity night Cancer Knights... Quickly after that launch will be a press and industry launch on October 7th. Once the club gets going, you can expect house business on Thursdays, and a selection of bass badness and other genre madness on Fridays each week. The new club has both intimate rooms and more cavernous spaces to create a variety of perfect atmospheres depending on the musical direction of the evening. Along with state of the art sound and light (including all manner of lasers, intelligent lights and big screens) there will also be garden and chill out areas for smoking and chats.
Previously one of London's best kept secrets, this new space is set to come alive in the wake of these new parties – once walking about in its insides, you can't fail to fall in love with the brick lined and closely encasing walls, atmospheric tunnels and inherent sense of misadventure... The club can and will be divided up into different rave spaces depending on the party and is as easy to get to as you could wish with great transport links. With the redevelopment of the South Bank and recent closure of SEONE there has never been a better time to come and check out Arcadia, right at the heart of London club land: as the name suggest, it's a utopian vision of clubbing perfection.
