After a few months of silence, we are finally able to speak out (online) that this has been our worst London-experience. Probably our worst life-experience.
You can read the review below this one (Joy L.) for the details, but basically my girlfriend got glassed in her eye here in December. Besides the fact that no CCTV was available on the basement floor (with such a crowded dark place, I might understand why this would be quite useless), it was the complete lack of professionalism, competence and help you would expect from a place like this. The bouncers and manager did not question anybody, did not take any details from the people who saw the person who did this (although in all the panic we requested that from them), did not call the police, did not file this case ... They even just put us in the cold stairway while awaiting the ambulance without any aid.
My girlfriend's sight and eye is damaged for the rest of her life and although they could not have prevented that, they were completely inadequate to handle this situation in any professional and helpful way. Because of them, we'll never know who did this and can never ask for any compensation.
