BFI IMAX

London's – indeed, the UK’s – biggest cinema screen at 540 square metres, the BFI Imax stands alone in the centre of a busy roundabout next to Waterloo station. Like a princess in a fairytale it’s surrounded by a labyrinth of eerie tunnels, which heroic filmgoers must brave if they wish to sample the delights within. But trust us, it’s worth it. The screen is, of course, absolutely massive, the sound quality is spectacular and the seats are arranged at such a vertiginous angle that there’s no chance of a head blocking your view. It’s not cheap – just over £20 for a premium seat – but if you like your blockbusters vast and noisy (and who doesn’t?) there’s really nothing else like it in town. One word of advice – locate your nearest loo before the film starts if you’re prone to a mid-film pee, because they’re all but impossible to find.
