Ozone Coffee Roasters

A working roastery and full-kitchen brunch spot near Old Street roundabout — the traffic circle at the heart of what's been nicknamed 'Silicon Roundabout' for the tech startups clustered around it — with exposed brick and black-framed windows doing the industrial-Shoreditch look properly rather than referencing it. Ozone is New Zealand-founded, part of the same wave of Antipodean coffee culture that reshaped London's cafés in the 2000s and 2010s, and roasts its own single-origin and house-blend beans at a separate Stafford facility, selling the results by the bag alongside brewing equipment in-store.

Weekend mornings run busy enough that the kitchen closes an hour before the espresso bar does, just to keep pace with the brunch crowd. It's as much a full breakfast destination as a coffee stop, and treated that way by most of the regulars who work in the offices and startups nearby during the week. Confirmed dog-friendly, with staff reportedly happy to provide a water bowl — a detail worth knowing if Old Street's tech-crowd energy isn't your main draw.
