This night at the plush Covent Garden Cocktail Club offers a choice of fancy dress. Either black and gold it up, or don your best thespy Phantom gear. But don't be fooled into thinking this'll be a civilised, restrained one – far from it. There'll be enough high spirits partying and raucous behaviour to keep anyone happy, and of course DJs playing party tracks and expertly mixed cocktails from the bar bods. But the real draw here? Confetti canons at midnight. Boom, literally.
