Claro London

You're walking past the grand Victorian facades of Waterloo Place when you spot Claro tucked away on this proper old-money stretch of St James's. Inside, it's all understated elegance—the kind of place where they've clearly thought about every detail, from the lighting to the glassware, without making a song and dance about it. The cooking is Mediterranean but it's not trying to be rustic or casual; there's real precision in the kitchen, evident whether you're eating a simply grilled fish or something more involved. The wine programme is brilliant—knowledgeable staff who'll actually help you understand what you're drinking rather than just pushing the expensive stuff.
