"The Baklava Latte has become the neighbourhood's signature order for a reason. Owner-run, laptop-free, with retail beans on the counter for when one cup isn't enough."

LIFT roasts under a numbered lot system, sources direct from named producers, and sells retail from the counter. The espresso is funky and fruity; the kind you describe by what's in the cup, not the postcode.
Hermanos roast their own Colombian beans, traceable to named farms, and serve filter alongside espresso at the bar. Ask the barista what's on today: they know the origin story and will tell it.
The owner roasts his own beans, tracks them to specific harvest lots, and pulls every shot from a kiosk inside Latimer Road station. Brazilian single-origin, rich and nutty, and he'll tell you which harvest you're drinking.
