Positano

You'll find yourself on Mayflower Street wondering if you've accidentally wandered into a trattoria somewhere along the Italian coast. The intimate dining room hums with conversation whilst plates of handmade pasta and wood-fired pizza emerge from the open kitchen with clockwork precision. The menu reads like a love letter to southern Italy, with each dish arriving as if the chef's been perfecting it for decades. Their risotto arrives creamy and al dente, whilst the seafood feels plucked straight from Mediterranean waters rather than the Barbican. Book well ahead – those 4.8 stars aren't just for show, and with only a handful of tables, you'll be kicking yourself if you miss out.
