OPSO

You're on Paddington Street where the postcodes get pricey, but OPSO doesn't play the Marylebone game of charging for ambiance alone. This is serious Greek food: charcoal-grilled octopus, feta so creamy it shouldn't be legal, and seafood that's been treated with real respect. The space itself feels like a very confident neighbourhood taverna—all marble, warm lighting, and the kind of buzz that comes from people actually enjoying their meal rather than performing it. Service moves at a proper pace, and the wine list punches well above what you'd expect, with Greek bottles you won't see everywhere.
