The Colombian Coffee Company

Something of a specialist, this Mayfair/Soho spot pours nothing but single-origin Colombian beans, championing distinct varieties such as Caturra, Borbón, Tabi and Gesha in the way a wine merchant would cite grape and region. Run as a social enterprise, it sources beyond Fairtrade to support the farmers and communities behind each harvest — and with a solid 4.6 rating from more than 560 reviews, plus both dine-in and takeaway, it has clearly earned its following.
