Colonel Saab Trafalgar Square

You're standing on William IV Street, just off one of London's most chaotic squares, but inside Colonel Saab it's all warm lighting and focused diners getting stuck into some genuinely excellent Indian food. This isn't the diluted curry-house stuff you might expect from such a touristy location—the kitchen knows what it's doing with spices, and you can tell they're not cutting corners to shift covers quickly. The menu pulls from North India with confidence, and there's a real sense that whoever's running this place actually cares about doing it right rather than just capitalising on foot traffic from Leicester Square.
