Coffee Island

Head down to Glaisher Street in Deptford and you'll find Coffee Island doing what so many London cafes claim to but rarely achieve: making coffee that doesn't taste like it's been sat on a warmer for three hours. The space has that unpretentious, no-frills energy that actually works—stripped back enough that you're not paying for Instagram aesthetics, focused enough that the people behind the counter clearly give a toss about what's in your cup. It's the sort of place locals actually return to, not because it's Instagram-worthy, but because the coffee is genuinely excellent and consistent.
