Went to the Clockwork Orange 20th Anniversary party there back in March. It was in Fire & Lightbox. That night was busy, and it was quite cramped in places. Security put in a one way system which eased things up a bit. Thought it was a great place for a party, but as with everywhere, I suppose it's what sort of crowd you get that makes the night. The vibe from the crowd on this night was absolute class!
Sound system and lighting was good.
Nice big outdoor area.
Only gripe was the taxi queue afterwards, but thats standard in most places I guess!
