WatchHouse

Doors open at 7am on weekdays — handy for early starts — with a gentler 9am opening at weekends, and there's outdoor seating, takeaway and wheelchair-accessible entrance and seating. This is the Canary Wharf outpost of a group that has grown from London all the way to Manhattan, with coffee, design and hospitality at its core. A 4.8 rating from 366 reviews suggests the formula is landing rather well.
