Sir Isaac Newton

You know the type of pub that gets busier the moment you sit down? That's the Sir Isaac Newton. It's positioned right on Castle Street, close enough to the town centre that you'll catch everyone from students to academics, but far enough removed that it feels like an actual neighbourhood spot rather than a tourist trap. The place has that comfortable, slightly worn-in feeling—wood panelling, decent ale selection, and the kind of crowd that actually lives in Cambridge rather than just passing through. Come for a proper pint and some solid pub food, and stay because you'll inevitably bump into someone you know.
