McDonald's

You'll find this branch tucked just off Rose Crescent, and whilst it's absolutely nothing groundbreaking, it does exactly what you'd expect from the golden arches. The location means it catches a steady stream of shoppers ducking out from the Grand Arcade, plus the usual mix of families and students looking for something quick and reliable. What sets this one apart is those weekend hours – staying open until nearly 5am on Fridays and Saturdays makes it genuinely useful when you're stumbling back from a night out in the city centre. The staff here seem to handle the late-night crowd with reasonable patience, and the standard menu hits the spot when you need something fast and familiar. It's functional rather than exciting, but sometimes that's exactly what Cambridge needs.
