I recently visited the electric ballroom for the second time. The first time i went was for a gig, and the second was for one of their club nights named "Sin City" which happens every friday. As i recall it cost me 6 pounds to get in. The club is located literally about three shops down form Camden tube station. Obviously there's lots of bus stops around too. So it's easy to get to. Staff all seem quite friendly. The contents of my bag were emptied upon arrival and i was patted down in a search by security. This was quite reassuring to see them being so thorough. Many door staff these days just open a bag and that's that. So i felt quite safe there. It's quite well sized, with two floors. This also means they can have two different types of music on each floor. There are two bars downstairs and there may have been a smaller one upstairs but i am unsure as i didn't spend much time there. They mainly play old school and new rock downstairs. Theres big dancefloor and a good air con system! There's a smoking area out back, some of which is sheltered for those of you that need it. Prices of drinks are what you would expect in central london. Red stripe being its main beer/lager and for about 2.80 a can and a house vodka and mixer was about the same. A good night out all in all. When i went to the gig there the prices we around the same. I went upstairs to watch the band after a while and you could see well. The toilets (girls anyway i cant speak for boys!) were clean and there was never any big queues as there was quite a lot of cubicles.
It has only been a year or so since I moved to UK and I canno say I have been to that many clubs locally, but I checked several where my favourite bands performed. But comparing even few: Astoria (which is so unfortunately closed now), Islington and Electric Ballroom plus the places in other countries I definitely give a positive 4 out of 5 to this place.
The gig I went to see was 69 eyes, Tiamat and Ava Inferi. So you can imagine the kind of music I am into - rather gothic, or at least doom metal.. And for that sort of music Electric Ballroom is absolutely a great place. Its not too big like Astoria, but rather good size and its Dark! The general audience seems quite alternative as well (well maybe it was due to the gig, but many of them seem to look like "locals").
The place has a nice bar as well which is on a side of the main area therefore you can sit down next to it and talk without being unable to hear each other.
Plus, it is located very much in centre of Camden, so very easy to get to even if you coming from outside London (I myself walked to and from Kings Cross station without problem at night).
