The self proclaimed "latest late-night bar in the West end" (although ironically only open till 1am) is a Shoreditch style sultry low-key hangout, with DJs spinning smooth Ibiza-style house tracks live every night.
Set in a dimly-lit industrial warehouse space, this place actually has no official dance floor, although the music and atmosphere usually get the crowd going all over the place. Climb the stairs to visit the impressive mezzanine champagne bar, or through the giant fixed steel chains to the VIP room.
If you're into the whole Ibiza-style club scene, Carbon's one to check out.
