Cakes & Bubbles by Albert Adrià

You're walking into the Café Royal on Regent Street—yes, that Café Royal, where Oscar Wilde used to hold court—but you're here for something altogether more frivolous and fun. Cakes & Bubbles is Albert Adrià's playful take on dessert, a place where the cakes are actually interesting (not Instagram props), and the champagne list takes itself seriously without being a bore. It's the kind of spot where you can swan in for a 3pm pick-me-up or linger over something properly decadent after dinner.
