Nostos Coffee

A roastery at heart, Nostos serves an ambitious range of single origins at its Westminster/Victoria base — from Ethiopian and Kenyan co-operatives to a honey-processed Costa Rican Geisha — with beans to take home or subscriptions for the truly devoted. Dogs are welcome at the outdoor tables, accessibility runs from entrance to toilet, and a 4.7 rating from 584 reviews suggests plenty of regulars think it's doing something rather right.
