"Opso is less humble taverna and more emergency spritz of Terre d’Hermès before a formal introduction to the tzatziki. Prices here would make Plutus proud, but it’s also bright, modern, and home to a sophisticated pavement terrace. Sipping mastiha cocktails out here is very Mykonos by way of Marylebone. But even on a grey day it’s worth visiting for salty octopus stew, the simplicity of honey-smothered imported feta, and the mini-break meal magnum opus, the mousakas." - sinead cranna, jake missing, rianne shlebak, heidi lauth beasley
