The Hut by The Heath

You'll spot The Hut nestled by the water at Hampstead Heath's Lido entrance—it's basically a small wooden cabin serving strong coffee and light bites to people actually using the Heath, not tourists looking for Instagram moments. The setup is wonderfully unpretentious: you queue, order at the counter, and either stand clutching your cup or perch on the few available spots while watching swimmers and sunbathers drift by. It's the kind of place where regulars know the staff by name and everyone's here for the right reasons—decent coffee and the outdoors.
