I've been there many times in the last months to see some friends playing, and generally I don't reccomend it as good club of East London.
Talking about the ground floor and the comedy cafe gigs, it's a really average venue, as you can find 100s in the area. Twice the sound was not amplified good (for a bass house night I think it's quite important).
The admission lady at the main entrance wasn't polite at all andthe bouncers were rude and aggressive even with girls, over reacting and treating people as shit. Also my friends have been charged more than the other people once.
Maybe they have a lack in the promotion too, some nights were empty with an old dj with no style, trying to pump up some old tunes.. it was quite embarrassing.
About the bar they sell cheap beers, cider and cheap wine, and the super alcool they only have the commercial ones.
Many more venues in the same street, with friendlier people and better vibes.
