First off, we head for the downstairs bar, which stretches the length of the main room. It's busy but gloriously queue-free. We girls order vodka and cranberry (£6 each), while Tom plumps for a bottle of beer (£6). The line-up for the night is fabulous: Fabian Chu, Filth & Splendour and Williams & Du Bois, with Tim Sheridan headlining. Not yet lubricated for dancing, we go upstairs, where there are more plush sofas, gilt mirrors and sweeping curtains, and you can look over the balcony to the dancefloor and a sea of sparkly dresses, jewel colours and silver shoes.
