Lussmanns Brasserie

You'll spot the solar panels and green credentials before you even step inside this Sun Street brasserie, but don't let the eco-warrior stance fool you into thinking it's all worthy kale and quinoa. The menu here is properly considered European cooking – think confit duck leg with Puy lentils or pan-fried sea bass with samphire – executed with the kind of technical skill that makes you forget you're doing your bit for the planet. The dining room strikes that sweet spot between smart enough for a date night and relaxed enough for Sunday lunch with the parents. Service knows the menu inside out, which matters when you're dealing with seasonal, local ingredients that actually change based on what's available. It's the kind of place that makes sustainability feel effortless rather than preachy.
