Situated off Rivington Street underneath two arches of the East London Line, the bar and club attracts an eclectic range of bands and DJs and a perfectly pleasant bar, garden and restaurant as well.
It's not even all try-hard Shoreditch rubbish and they occasionally have proper bands playing, or even special nights of reasonable quality stuff. The main performance space, beneath the second arch, has a great atmosphere, but is easy to escape if you need a breather.
All in, it's a good place, and probably has an interesting history or something, or maybe it's brand new, not sure really. For more, see http://www.cargo-london.com/
