10 Paddington Street, W1U 5QL, London https://www.opso.co.uk/ £9-£19; Mains: £16-£68; Wines from £58 by Derick RethansOPSO styles themselves as a modern Greek restaurant. They're based just off Marylebone High Street. Wine starting at £58 is a bit of a joke really… but it's Marylebone, so perhaps the locals don't notice or care? For our mains, we shared the slightly seared tuba, which was dressed with sugar snap peas, tomato, mint, and capers. The food was delicious, and the atmosphere lively, but we did think that perhaps some value has been lost along the way.
