Burger & Lobster Knightsbridge
Seafood in London with a kids menu and highchairs — 4.7★ (8,057 Google reviews).
Café · Westminster
Perched on the fifth floor of Harvey Nichols in Knightsbridge, this café and terrace has a relaxed, grown-up feel with a seasonal menu that takes food seriously — think proper set lunches with carefully chosen ingredients rather than anything rushed. It's more than capable of handling families, with highchairs available and a kids' menu to keep little ones sorted, and the terrace gives everyone a bit of breathing room. Buggies can be accommodated, though there's no baby-changing on site, so it's best suited to families with slightly older children.

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.
