I do not see why this article should be considered for deletion. It is a music venue in London and is very well known.

Here are some examples of music venues of a very similar size and nature, also in London, which have not been deleted from wikipedia: 

http://en.wikipedia.org/wiki/The_Angel%2C_Islington
http://en.wikipedia.org/wiki/Hope_and_Anchor%2C_Islington
http://en.wikipedia.org/wiki/Dingwalls
http://en.wikipedia.org/wiki/100_Club
http://en.wikipedia.org/wiki/Jazz_Caf%C3%A9

Surely if this page is deleted then they should be too?

If the style is not satisfactory, hopefully someone will rewrite it later. There is blatent critism of the venue on the page. Surely someone doing self promotion would not include this??
