180 Health Club

You'll find this place buried in the bowels of 180 Health Club on the Strand, right in Temple—basically where the lawyers and accountants go to pretend they'll get fit. It's not fancy, and that's rather the point. Walk past the gym reception and you'll spot the smoothie counter, all businesslike efficiency and zero faffing about. The drinks are straightforward (proper fruit, actual protein, no added nonsense), and it's the kind of place you'd genuinely pop into before or after a workout, not somewhere you'd linger over an oat milk cappuccino for three hours. The vibe is pure convenience—grab, sip, go—but the ratings suggest they're actually doing the basics properly, which is refreshingly rare in central London.
