KOKO is based right near Mornington Crescent tube station in Camden and is one of my favourite live music venues / clubs in London.
Previously a theatre, the venue is designed beautifully over several tiers with balconies either side. There is a massive dance floor by the stage that stretches right back to the bar. There are 3 different bars to get a drink but they still get packed.
KOKO holds a variety of nights including Club NME, which is more indie / rock music and Guilty Pleasures, which is mainly cheesy music with stage acts and sometimes massoake (mass karaoke). Great sound system.
Really great night out!
