Sticky Mango

You're walking along the South Bank near the National Theatre when you spot Sticky Mango tucked on Coin Street—and honestly, it's worth the detour. This is the kind of Thai restaurant that doesn't apologise for its flavours or dress things up unnecessarily. The menu reads like someone's actually eaten their way through Thailand rather than just riffed on what they thought British diners wanted. Expect proper heat if you ask for it, pungent fish sauce where it belongs, and portions that won't leave you eyeing the person next to you's plate. The riverside location means you can watch the Thames life unfold while eating something that actually tastes alive.
