Attendant Coffee Roasters - Mayfair

You'll find Attendant tucked away on Duke Street in Mayfair, which is saying something given how aggressively polished that postcode usually is. Walk in and you're met with the smell of freshly roasted beans—the kind that makes you forget about every mediocre flat white you've had in chain cafés. The space itself is straightforward: counter-focused, no twee reclaimed wood or industrial Edison bulbs trying too hard. It's the sort of place where regulars actually know the staff and the staff actually care about dialling in your drink, not just moving through the queue. They've got their own roastery operation happening, which means the coffee has serious backbone—you can taste it.
