Ground Coffee Society

Part cafe, part roastery, this Putney spot pairs hand-roasted single origins — think Ethiopia, Rwanda and Kenya — with a farm-to-cup focus on ethical, sustainable sourcing. Dogs are welcome at the outdoor tables, step-free access runs throughout, and the 7am weekday openings make it a natural first port of call for early risers. With a 4.5-star average from nearly 700 reviews, it's clear the neighbourhood approves.
