Canada Square Park

You'll stumble into Canada Square and immediately clock the contrast: all that corporate steel and marble, but somehow it works as a proper public space. The plaza sits right on the water's edge, with the Dock beyond it, and there's actually room to breathe here—benches scattered about, some greenery, and the kind of light you get in East London when the sun bounces off the Thames. It's not pretending to be a village green, and that's exactly why it doesn't feel like a corporate wasteland. Come summer, there's live music and outdoor cinema; come winter, it gets moodily quiet. Grab a coffee from one of the nearby spots (Pret, independent cafés tucked into the surrounding buildings) and post up for an hour.
