Fenix Restaurant Mayfair

You're walking past the Georgian elegance of Stratton House on Piccadilly, and Fenix sits there like it's always belonged—because it has, in various guises. Inside, there's marble, leather banquettes, and serious wine racks that actually mean something. The cooking is unshowy Italian: proper pasta, pristine seafood, the kind of plates that make you understand why people book weeks ahead. It's the sort of place where you can eat brilliantly without feeling like you're being performed at—refreshing for Mayfair, honestly.
