Chinese · Mill Hill
The Good Earth is a well-regarded Chinese restaurant on The Broadway in Mill Hill, known for turning out genuinely impressive food — reviewers regularly call it among the best Chinese cooking they've had in London, with the set menu often flagged as particularly good value given the quality. It's a proper sit-down, atmospheric place that gets very busy, so booking ahead is wise, especially at weekends. Highchairs are available and the restaurant is easy to navigate with a buggy, though there's no outdoor space or baby-changing facilities, so bear that in mind with very little ones — and note it's on the pricier side, though most families who've made the trip feel it's worth it.

The secret to a calmer meal out? Something to do that isn't a phone. Each pack is full of screen-free bits and bobs to keep little hands busy at the table and buy you a proper sit-down. Three printable packs, one for each age (toddler, preschool, primary) — free, straight to your inbox.
