cloudM Tower of London

You're standing 40 storeys up in Tower of London, drink in hand, watching the centuries-old fortress light up below you. cloudM is citizenM's rooftop offering—all floor-to-ceiling glass and that intoxicating feeling of being suspended above the City. It's the kind of place where you clock the Shard, St Paul's, and the Thames snaking through, all at once. The crowd skews smart-casual: after-work types in their best shirts, dates who want to impress, locals who've finally bothered to climb up. Cocktails are proper (not gimmicky), the beer list knows what it's doing, and the service doesn't treat you like you're interrupting their evening.
