Donostia brings the flavours of San Sebastián to the heart of Marylebone, serving some of London's finest Basque cuisine. If you can, grab a seat at the counter, where you'll have a front-row view of the kitchen and the rhythm of service. While everything deserves a mention – from the perfectly balanced pan con tomate to the exceptional seafood – the true highlight arrives at the end. Their ultra-creamy Basque cheesecake, with its deeply caramelised top and rich, almost toffee-like flavour, is worth saving room for every single time.
