Old Spike Cabot Square

There's real substance behind the counter at this Canary Wharf coffee shop: it belongs to Old Spike, the South London roastery whose coffee sales help fund an employment programme offering training, paid placements and job support to people experiencing homelessness. It keeps weekday hours only — 7:30am to 4:30pm, with an early 2pm finish on Fridays — and earns a strong 4.7 rating, with both takeaway and dine-in service.
