Core byClare Smyth

Clare Smyth left the Gordon Ramsay group to open Core, her own restaurant, in Notting Hill in 2017 — and turned it into one of a handful of British restaurants to hold three Michelin stars, cooking a refined, produce-obsessed British menu under her own name and control. It is an independent single venture, not a group asset, run by a chef widely rated among the best in the world. This is the top of the tree. Book a very long time ahead; go for a very long lunch.
