Department of Coffee and Social Affairs

You'll find yourself on a quiet courtyard just off the madness of Carnaby Street, which already feels like a small victory. Department of Coffee is the sort of place where they've clearly thought about every detail—the beans, the water temperature, the pour-over technique—without making a fuss about it. It's got that deliberately understated London café vibe: blonde wood, minimal décor, proper espresso machines, and the kind of staff who actually know what they're talking about. You can grab a flat white and a pastry, sure, but you'll also find single-origin filter coffees and seasonal specials that change depending on what's worth drinking that month.
