Loewe

You're on Oxford Street—that mad stretch of high street chaos—but slip into Loewe and suddenly it's all minimalist calm. The space mirrors the luxury fashion ethos of its Fitzrovia surroundings, all clean lines and curated simplicity. You'll find proper cold-pressed juices here rather than the syrupy stuff you'd expect from a casual smoothie spot, and the blends actually feel considered. It's the kind of place you'd grab something green before heading into Browns or a fitting room, or linger with a beetroot and ginger if you've got time.
